I used to do this in London when I traveled there for lectures as a PhD student; our lab wasn't in the city. So as not to waste two hours of traveling for an hour of class, I'd go and see movies afterwards. It was great - you could get the best cinemas to yourself and I liked trying out the different venues around Leicester Square. My favourite was the underground one near Piccadilly Circus (now Vue I think) - always empty midweek just after lunch and comfortable seats. I'm not a fan of the enormous screens because they tend to echo quite a lot unless the acoustics are good. Perhaps the sound gets damped when the room is full?
