Just watched The Imitation Game and I highly recommend it. Benedict Cumberbatch delivered an Oscar worthy performance for portraying Alan Turing, the father of theoretical computer science, in the film. If you've ever taken Computer Science fundamental theory courses in college and hated Turing machines, then watching this movie might change your mind.
Also a shoutout to Alex Lawther, who played young Alan Turing in the movie. That was a superb performance too.
