I tried to edit the OT into a 3 in 1 movie, I consider it a failure.

For one, 3 in 1 prequel edits work because the prequels have a ton of filler, and the OT doesn’t really. There is a ton of stuff you could cut (the point of my 3 in 1 edit was to have one single Death Star, so obviously the Death Star attack in ANH could go), but not nearly as much. I couldn’t really get it shorter than 3h55, and I cheated by speeding it up from 23.976 FPS to 25 FPS.

Secondly, I felt like having the Jabba’s Palace sequence in the same movie as Han getting frozen in carbonite was… bad? It felt like backtracking, although I could also see it being like a chance to see more of the universe? In a meta way?

I don’t know. Don’t let this discourage you, rocknroll41’s idea especially seems promising. I’m just warning you it’ll definitely be hard to get to work.
