In the first scene of the trailer for 50/50, Joseph Gordon-Levitt is attempting to shave his head, using an electric razor his friend Seth Rogen has probably used on his private parts. It looks like the set-up for a new Judd Apatow knee-slapper, but 50/50 is no Knocked Up. Based on the true story of how screenwriter Will Reiser overcame cancer, the film takes a lighter, humor- and romance-filled look at what life is like when you have a 50 percent chance of dying young. The trailer looks promising, and we’re excited about the cast, which includes Anna Kendrick, Bryce Dallas Howard, Anjelica Huston, and Philip Baker Hall in addition to Gordon-Levitt and Rogen. Let us know whether you plan on seeing 50/50 when it comes out September 30th.
