What did you do this weekend?

ask him or her what they did.
was it boring?
did you like it?

also talk about movies.
did you see _________??
what did you think of it?

after you guys are comfortable you should ask him or her to go see a movie together.
specially a funny one so you can laugh and have a good time.

maybe afterwards you can go to the movies once a month together or something and you will have a stronger realtionship....
