A man wakes up, wearing only boxer shorts. He is trapped in an environment that is sort of like a fun house, that has a picture of someone that looks a bit like Haile Selassie. Years evidently pass. He lets himself go physically, but then gets into shape by doing exercises he see on a video screen using objects in his environment like books as weights. Time passes. He is shown video of what I assume is his wife and daughter, who plays the cello.
That's what I remember (I saw this on someone's screen (no sound) in an airplane, but fell asleep). Does anyone know what (recent) film this is?
