I’d heard great things about it so walked across Central Park to the Lincoln Center near Columbus Circle as that is the only theater in NYC that’s playing it. Oh, here’s a link to an overview of the movie: http://www.imdb.com/title/tt1483831/
I won’t reveal any spoilers, but I will say it wasn’t quite what I was expecting. It was clear what the director was going for, but the execution didn’t quite pull it off. It’s been described as Das Boat in a tank, and that’s fairly accurate except Das Boat is a superior film. Still, there were elements in the claustrophobic environment of the tank that I thought superb. One of the best was the narrative device of the disembodied voice of a commander heard over the radio. It’s no easy feat to make a movie that takes place almost entirely inside a space about the size of a 10×10 closet. What gripes I have are more with some of the acting. I thought a couple of characters were a bit over-wrought at times.
In the end, I do recommend this film. The banter between the tank crew is quite hilarious at times and there’s one great story told about a teacher and a father’s death that while seemingly out of left field is a fascinating bit of story telling.
