I'd imagine something like the Wampa attack might have happened even if Mark hadn't improved his face with a car crash.

Wampas are basically Yeti (just as Wookiees are Sasquatch) and the attack riffs the Tuscan scene in the first film (both end with an arm on the ground) just as the Imperials being picked off attacking the reactor to knock out the Rebel spherical weapon mirrors the rebels being picked off attacking the reactor of the imperial spherical weapon in the first film.

The escape pod carrying droids mirrors the landing capsule carrying the probot.

In the lost cut of Star Wars (1977) Luke is looking up at the sky with binoculars and this gets recycled in ESB.

Just something Bingo brought up on another thread about the ANH-ESB relationship.

I find some of these repetitions between the movies quite interesting, as they can be used to address how a character has developed by having them deal with a situation differently.

There are some obvious repetitions between ROTJ and ANH with the Death Star (which really don't achieve this at all), but I was wondering if any events or interactions could be built to repeat constructively?

The only one I could think of first, was to re-edit the SAIL BARGE ASSAULT to mimick the FALCON ESCAPE from bespin. The heroes could just fight and escape on the skiff, and not necessarily destroy jabba and his sail barge (it always felt too much like an overpowering victory romp to me, when that sensation should be saved for the end of the movie). The musical ques could be also be altered so they match the scene from ESB.
