Trivia: In the 1996 novel "Shadows of the Empire," it is revealed that Dash Rendar was one of the snowspeeder pilots during the Battle of Hoth.
Trivia: There are two additional scenes that are not included in the special edition. The first one is near the beginning when Han is asking if Luke has made it back, you will notice that there is a slaughtered Taun-Taun on the ground. In the scene they discuss that something has killed it. Later, the Ice Creatures attack the Hoth base and get locked in a storeroom. A sticker is placed on the door saying do not open. In some of the promotional materials there is a shot of C3PO peeling off the sticker. Stormtroopers open the door and get killed. When Vader enters the base, he asks 'What killed these men?' After all, they had to blast into the room, and it's already full of dead Stormtroopers.
Trivia: THX-1138 is referenced when, on Hoth, General Rieeken says "Send Rogues Ten and Eleven to station three-eight."
Trivia: A special effects technician added a tennis shoe to the asteroid scene. It can be seen flying from the central-left side of the screen to the lower right. It's right at the beginning of the exterior shot after Han Solo announces that he's going for one of the larger ones, and Leia, C3PO, and Chewbacca voice their objections. (00:39:40)
Trivia: Right before the first transport is away, there is a shot of Leia and others in the control room on Hoth. During this scene a clicking and screeching sound can be heard. It sounds like a clock ticking. This is a recording of a shortwave radio station CHU from Canada, complete with the second ticks.

Trivia: Lobot's name is never mentioned in the film, and in the end credits he is simply listed as "Lando's Aide."
Trivia: The name "AT-AT" is never spoken in the film. Instead, the machines are only referred to as "Imperial walkers."

Trivia: The facility of Cloud City is never referred to by name in the film..
Trivia: In Cloud City, when Chewy finds C-3PO in pieces in what looks like a droid scrap room, you can see what looks like the upper half of IG-88 leaning up against the wall. It is revealed later in books to be the IG-88 unit that went in search of Han, but was intercepted and destroyed by Bobba Fett.
Trivia: When Han Solo fires shots from his blaster at Darth Vader in Cloud City, the weapon zips into Vader's hand. To achieve this effect, director Irvin Kershner threw the gun across the table and the crew photographed a quick take of the gun flying through the air and then put a string on it, put it in the hands of Darth Vader and pulled it out with the camera upside down.
