We’ve got a few quick casting stories for you this afternoon.  First up, Tobey Maguire has joined the cast of Jason Reitman's Labor Day.  The film "centers on a 13-year-old boy who convinces his reclusive mother to take in a drifter over Labor Day weekend.  It’s later revealed that the man is an escaped convict and the three spend a weekend together that will shape them for the rest of their lives."  According to Deadline, Maguire will play the adult version of the boy, and Maguire also narrates the film.  He joins Kate Winslet, Josh Brolin, J.K. Simmons, Brooke Smith, Gattlin Griffith, and Brighid Fleming.  I haven't seen enough Maguire in theaters lately (his last movie was 2009's Brothers), but his film The Details, which played at Sundance 2011, will finally see the light of day in September, and I'm looking forward to his portrayal of Nick Carraway in Baz Luhrmann's The Great Gatsby this December.Hit the jump for casting news on new additions to Drinking Buddies.  Filming on Labor Day begins later this month in Massachusetts.According to Deadline, Olivia Wilde, Ron Livingston, and Jake Johnson have joined the cast of Joe Swanberg's indie improv comedy Drinking Buddies.  As we reported yesterday, Anna Kendrick will play the female lead in the movie, which "centers on a fun and flirtatious friendship that goes off the rails."  Livingston will play the male lead, but there are currently no details on Wilde or Johnson's roles.  Filming on the micro-budget flick is set to begin later this summer in Chicago.
