What are some interesting movies/books to safely share at work?

So I'm totally introverted and socially awkward. I really want to fit in at work and try to socialize more. There are always discussions about movies and books. I've been in survival mode for the last 5 years due to health issues and have not had time to even think of these things. I can't even think of any that I would say are my favorite. Plus it's hard to think of movies and books to mention at work that are appropriate. Please give me some ideas that would be good to bring up at work to be interesting and help with conversation. but appropriate for work!
