Luke's legs are closer together in the close-up of the cave ceiling.
If you look closely at the Wampa's arm, you can see where the fur ends and a sleeve begins.
Luke manages to slice off the Wampa's arm. It seems like, rather than running out into the frozen darkness, he might've finished off the creature and spent the night in the relative shelter of its cave. More...
Anakin is supposed to be traveling incognito, though his distinctive Padawan haircut is visible to all.
When Yoda turns to protect Obi-Wan and Anakin, Dooku could attack the Jedi Master, instead of running away. More...
It's a good thing none of the denizens of Jabba's palace sleep near the carbonite, or Boushh could never get near enough to free Han undetected.
Leia doesn't yet know that C-3PO is mistaken for a god when she tells the droid to order the Ewoks to release the captives. More...
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.

On a space ship, "down" is determined by artificial gravity. Therefore, if the ship is damaged and begins to tilt, those inside would not begin to slide across the floor; gravity would keep them oriented to the floor, no matter what position the ship was in. The only way our heroes could experience the "Poseidon Adventure" effect would be if the artificial gravity controls malfunctioned. And what a strange malfunction, as the gravity continues to shift a millimeter at a time until everything is upside-down!
"Only a Sith deals in absolutes," cries Obi-Wan, although his statement is itself an absolute.
Be sure to tune in!
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.
