Acid has a longer duration and tail, and I also think it often affects people differently than mushrooms (it does for me), and as said ^ having any kind of constraint, even a fun one like Star Wars, can be a big factor in making you feel uneasy so I definitely wouldn't plan it on the same day. If you are more experienced then you could intentionally go see a movie during the afterglow but that is a different story and it requires plenty of previous experience with how you react to going out in public while still tripping a bit, and activities like going to the theater. At the very least you'll want to know what to expect by having at least some previous experience (with acid in this case).
There shouldn't be any hurry so try to change your mind and don't be 'set' on doing something that is very inconvenient related to tripping.
Besides, doing acid for the first time tends to be pretty incredible so even if you could pay enough attention to the movie as you'd like, planning two major events on the same day just sets you up for one of them eclipsing the other at least a bit.
