Keeping on a theme in line with my interest in space travel and the future, my favourite film of recent times is Oblivion (2013), starring Tom Cruise.
I love the concept that (for once), mankind only thinks that they've defeated an enemy, and the film takes you along with Jack Harper Tech-49 as he discovers memories that he shouldn't, which provoke a dawning realisation that something should be done before it's too late for mankind. Highly recommend this film for anyone who understands science fiction and is interested in the subject generally.
