“That’s not what the truck looks like” is what’s wrong with how some view Star Wars. The Force can be used to influence minds. That’s the “trick.”
I don’t know what you’re saying. Luke does two things when he enters the palace, he raises his hand and chokes two guys with blatant visual and audio clues - exactly like Vader. Then he goes inside and tries to ‘trick’ Jabba with spoken words - just like Kenobi. Both are distinctive, and they are shown just as they were in the previous two movies. How are you getting the old ‘you don’t need to see his identification’ gag mixed up I don’t know, especially when he does it in the same scene. You think he did the same thing twice?
