"What is the most recent movie you saw?"
You can either answer by using a similar answer to the recent book question, or you can say that you don't watch movies that much.
"The last movie I saw was The Last Samurai. I thought it was great."
"Oh gosh... it's been a while since I've seen a movie. I think it was Spider Man. I like to spend my time outside, so I don't see movies that often."
Both of these answers are fine. Whether you like to see movies or not, just tell them exactly what you think. Your answers will be more natural. If you answer these types of questions awkwardly, they might get the impression that you are uncomfortable or that you are not capable of small talk. So answer without thinking too much about these questions.
