If the question is "Tell me about a movie you enjoyed RECENTLY", then your answers ("I haven't seen any movies recently", etc.) would be appropriate. However the word "recently" isn't in the question, so you can talk about a movie you saw 10 years ago, if you like. Some useful sentences: "My favourite film is..." "One movie which I really liked was..." "I really enjoyed..." If, however, it's been so long since you watched a movie that you can't remember a movie you enjoyed, you can say "It's been so long since I've watched a movie that I can't think of any good films right now"! By the way: this question sounds a little like it comes from a speaking test. If so, then just saying you can't remember might not be the best option :-P

Hi Milena, 1) Yes, it does convey that meaning, except that you should say: "It's been a long time since I've watched a movie" or if that's true for you: "I have never watched a movie" (if you truly haven't seen any movie yet) or "It's been a really long time since I've watched a movie"
