What can I get a Star Wars fan for Christmas?

My bf is a huggggeeee Star Wars fan and I’ve never seen more than 10 minutes of any of the movies. I am actually interested in watching them because in some way we can bond over watching all 289023849898 movies. He doesn’t actually own any of the movies but has seen them more times than we see the sun in a year. So my problem is that I have no idea what order the movies go in/if some are better to get than others/if this is even a good idea. I need help from Star Wars fans because I’d actually like to watch them and understand them but trying to figure this out is kinda like trying to read Chinese. Also is there something else maybe I can get him? We’ve been dating for a while but anytime a holiday/birthday comes around we enjoy doing things together more than gift buying which is why I figured getting and watching the movies would be fun.
