The Big If movie is Summit Entertainment’s 50/50. It stars four of the hot young actors of Hollywood -- Joseph Gordon-Levitt, Seth Rogen, Anna Kendrick and Bryce Dallas Howard -- so what’s the Big If? Well, if audiences can get past that it’s about the Big C, then it may enjoy solid box office returns. Cancer has played a role in a number of films and TV shows, including comedies, in recent years, so this may be no handicap.

Meanwhile, Sony Classics’ Take Shelter, from director Jeff Nichols, stars the ubiquitous Jessica Chastain and one of the top American characters actors, Michael Shannon.
