In the hangar of the Trade Federation ship, Qui-Gon says "Battle Droids" in a surprised tone, although the Jedi already saw and fought Battle Droids on board the ship. Now if he'd made a comment on the large number of Battle Droids...

Anakin's bedroom is filled with interesting sci-fi parafanalia, including a bowl-shaped object with a handle hanging near the door that appears to be formed of thin black plastic strips. This is a toy that was sold on Earth sometime in the '80's under the name of Trac Ball.

The decoy queen gives Padmé, the true Queen Amidala, the task of cleaning up R2-D2, a dirty job she could've alotted to one of the true handmaidens just as easily.

The citizens who elected Queen Amidala probably know that her first name is Padmé. Wouldn't that make it dangerous for her use her real name when posing as a handmaiden? Or is Padmé just a super common name?

Anakin builds a protocol droid to help his mom. It doesn't seem that a slave would have much use for a protocol droid. Perhaps a housework droid or a manual labor droid would've been more appropriate.

Capt. Panaka says one of the candidates for the new supreme Chancellor is Bail Antilles. Earlier, we heard that Bail Organa was in line for the job. Is this a glitch, or are two men named Bail actually in the running?

Obi-Wan lands his fighter in the pouring rain, exits the craft, takes about five steps, and then, when it is too late to do him any good, puts on his hood.

Padmé pushes a button on the ship's control panel to send a message to the Jedi Council. She pushes the exact same button to display a star chart.

Artoo can fly. Wait...he can fly?!?

Most of the things Obi-Wan tells Luke about his father in Episode IV turn out to be true, at least from a certain point of view. Except for that business about Skywalker Sr. wanting Luke to have his lightsaber when he was old enough. If Anakin had any such wish, he couldn't have told it to Obi-Wan since the latter didn't even learn about Anakin's pending fatherhood until after the two Jedi were beyond the point of making friendly small talk.

When Artoo is sliding across the deck of General Greivous swiftly tilting ship, why doesn't he just fly above it?

General Grievous has enough organic parts to cough, but his breathing is unaffected by the vacuum of space.

How does Padmé find Anakin in the Mustafar system? Maybe that's the only habitable part of the planet.

"Only a Sith deals in absolutes," cries Obi-Wan, although his statement is itself an absolute.

It takes twenty-some years to build the first Death Star, but only a few months to build the second, at least to the point where it is fully operational.

Why does Obi-Wan have Threepio's memory erased, but not Artoo's?

Some Stormtroopers are definitely shorter than others. Are these defective clones?

That plastic armor worn by all Stormtroopers isn't very effective. It never takes more than one blaster shot to down a Trooper.

Threepio, after being jettisoned in an escape pod, looks back and comments that the damage doesn't look so bad from out in space. Is he referring to the rebel ship he just left? Because the only ship we can see is the Imperial Star Destroyer, which probably wasn't damaged a whole lot from the battle with a tiny consular ship.

When Owen purchases R2-D2, there is suddenly an R5 unit beside the droid, even though it blew its motivator only moments before. That's because it's actually a bit of reused footage of Artoo.

While Luke is eating with Uncle Owen and Aunt Beru, the cup in his hand jumps around quite a bit to and from his mouth and from one hand to the other.

Ben Kenobi seems not to remember Artoo or Threepio at all. Sure, it was a long time ago, but they played a pretty big role in his life, and he personally hid them with Capt. Antilles, good reasons for the droids to be indellibly seared in the Jedi's memory.

The sound on the hologram message is sometimes out of sinc.

The Leia hologram says that her mission to bring Obi-Wan to Alderaan has failed. Good thing! If it had succeeded, he would have died with the rest of the planet. What exactly was Leia's plan, I wonder, once they arrived on Alderaan? We'll never know...

When Tarkin discovers that Princess Leia has lied to him about the location of the Rebel Base, he angrily orders Darth Vader to terminate her immediately. Obviously, Vader never complies. He later comments that she may yet be of use. This must be some new definition of the word "immediately."

"Only Imperial Stormtroopers are so precise" with blaster fire, says Ben Kenobi. Only, Troopers aren't all that precise during the rest of the film. In fact, they miss our heroes quite often.

Han boasts that the Milennium Falcon made the Kessel Run in less than twelve parsecs. A parsec is a unit of distance, not time.

Ben Kenobi specifically states that he wants safe passage to Alderaan with no questions asked. Naturally, the first thing Han does is ask if it's some kind of local trouble. What part of "no questions" didn't you understand?

As Luke and Obi-Wan head for the Milennium Falcon to leave Mos Eisley, a long-nosed alien spies on them; while alerting the Stormtroopers via his comlink, the alien's nose gets in the way and he socks himself a painful-looking blow. You'd think he'd be used to the size of his own nose.

When 3PO mentions Princess Leia by name, Luke reacts, even though the hologram message never gives her name. Ben must've talked with him about the princess onboard the Falcon.

That catwalk leading to the tractor beam control is awfully dangerous without a railing. Have any technicians fallen off, I wonder?

Leia states that it won't take the Imperials long to figure out that they've escaped down the garbage cute, nor should it. But no Stormtroopers ever show up at the door to capture our heroes.

In the garbage compactor, you can see Luke mouth the words, "What was that," but can't hear him say anything. Maybe he's whispering.

Luke is almost killed by the Dia Naga, while Chewie stands off to the side, futilely pounding on the door. A little help, please...

Leia's hair is a mess when she exits the trash compactor, and no wonder, with all she's been through. Only it looks a lot neater when she and Luke meet up with Han at the Falcon.

Leia shouts, "They're coming through!" well before the Stormtroopers begin to open the door.

Some shots of Leia and Threepio in the Yavin control center are reverse images.

We hear an announcement that the rebel base will be in range in thirty minutes, but the on-screen counter is moving much too fast to be counting down minutes. Actually, the numbers on the screen are often different from the numbers that are announced.

We hear someone ask over the com system, "Red 6, can you see Red 5?" Too bad Red 6 is already dead by this time.

A message is sent to Red Leader that Tiree and Hutch are gone, to which Red Leader answers, "I copy, Gold Leader." Hey, buddy, Gold Leader's already dead. You're talking to Gold 5.

Although it's hard to hear, when Leia rushes to hug Luke after the destruction of the Death Star, young Skywalker happily shouts, "Carrie!"

Nobody can pronounce Han's name correctly in this episode.

Somewhere between the destruction of the Death Star and the beginning of this film, Darth Vader learns Luke's identity. At the end of Episode IV, Luke was just a nameless rebel pilot to Vader.

Luke appears to have found time for a haircut after his release from sick bay.

Luke says the armor on the Imperial Walkers is too tough for the Snowspeeders' blasters, yet once the AT-AT falls over, the blasters destroy it easily enough.

Ben tells Luke to go to the Dagobah System to find Yoda. But he never says which world in the system to visit. Maybe the system only has one planet.

Luckily, Luke lands his X-Wing very near to Yoda's home, considereing he had an entire planet to search.

Trying to hide from the Imperials, Han flies the Falcon into a cave in an asteroid, unwittingly entering the mouth of a giant space slug. The creature or the asteroid must have its own atmosphere, because Han, Leia, and Chewie are able to walk around inside it without any type of space suit.

Luke tells Artoo to stay and watch over the camp. So what is the droid doing away from camp, peeking in Yoda's window?

Does Darth Vader kill Captain Needa? He seems to move when the gueards carry him away. Perhaps the Sith Lord was merciful this time.

Although Anakin built C-3PO himself, we see another virtually identical droid. Did Ani use a kit?

Lando says that Darth Vader and friends arrived in Cloud City just before the Falcon. How? Boba Fett followed them to Bespin and must've contacted Vader to relay the Falcon's destination to the Sith Lord, who somehow managed to get there before Han.

Yoda tells Luke that he will destroy everything his friends fought for if he leaves to help them, a prediction of Yoda's that definitely did not come true.

At the very end, Lando is shown in a white shirt and black vest. Is he wearing Han's clothes?

Lando still can't pronounce Han's name.

When Han is defrosted, he's not wearing the upper-arm restraints he had when entering the carbon-freezing chamber.

Right before swinging off the barge, Luke says, "Come on," without moving his lips.

Is it an optical illusion, or can you see right through the Emperor's hand when he arrives at the Death Star?

Ben Kenobi tells how the Skywalker infants were hidden from Darth Vader at birth. But why not change baby Luke's last name as a precaution?

The Endor landing party is well camouflaged for their trek into the forest--all except for that shiny gold-plated droid who stands out like a beacon.

Luke and Leia don't even try to shoot the Imperial Biker Scouts until they are fired upon by one. Perhaps they didn't know the things had weapons until they saw them in action.

Luke travels miles and miles on the speederbike, then walks back to Han. Maybe he was flying in circles...

Where did Leia get that buckskin dress she wears in the Ewok village? Does she always carry it on dangerous missions? Or do the Ewoks keep extra clothes around for large visiting aliens?

C-3PO complains that it is against his programming to impersonate a deity, yet he does so, upon Luke's orders. Does the Force work on droids?

Threepio enthralls the Ewoks with tales of his adventures, even though he said in A New Hope that he wasn't very good at telling stories in an interesting fashion.

Leia says that she remembers her real mother as beautiful and kind, but sad. While these things are true, it would be impossible for Leia to remember them, since Padmé died minutes after giving birth.

The Imperial commander tells his men to "bring those two down here," referring to the droids. I can't see Artoo in that shot, can you?"

Look closely at the band of rebels held prisoner by the Imperial troops on Endor. Among them, standing with his hands on his head, is that Biker Scout they captured earlier. Guess he couldn't convince the Stormtroopers he was on their side.

To trick the Imperials into opening the bunker door, Han puts on a helmet and radios them from inside a scout walker that all is secure. By the time the doors are opened, he is on the ground next to the bunker door sans helmet. While this would be possible if the Imperials were relatively slow to come out, it seems like a waste of energy for Han to rush over there when other rebels could easily have taken care of things.

Annakin's ghost is dressed exactly like Yoda and Obi-Wan, a costume he never wore in his lifetime.
