I personally allways interpreted the scene as signifying Luke’s a darker character now, and more like his father than he might think. So, to me that allways was a case of Luke using a Force choke, but if Hamill or anyone else sees it differently, I suppose only George Lucas has the answer. The ROTJ screenplay doesn’t speak of a Force choke, so you may very well be right.
Which scene are you referring to?
ROTJ at Jabba’s palace when Luke force chokes the pigmen to gain access.
There are a few people here who believe Luke was using a mind trick to make them go to sleep.
Which I’m incredulous at…though I guess I shouldn’t be surprised.
