buried

this is an impressive experiment.  they say that when you put limits on art it forces you to be more creative and work smarted to try and overcome those limits.  i cant think of a movie that had more limits placed on it than this film.  they whole thing is set in a wooden box the size of a coffin.  ryan reynolds stars as the only actor in the film (other than a voice or two on the other end of his cell phone).  he finds himself buried alive and has to try and figure out what went wrong and how to get help to get out of there!  the whole thing is surprisingly intense and exciting.  for all its limits, its still quite dynamic and interesting.  the developments and turns the plot takes along the way work well and leave an intense finale.
