According to Variety, Chris Cooper is joining the cast of the Weinstein Company’s upcoming “August: Osage County”. Meryl Streep and Julia Roberts are already on board to star in the picture, which focuses on the Weston family, a group of people who have to get past their personal differences when the alcoholic husband of Streep’s character goes missing. Cooper has signed on to play Streep’s brother-in-law. With Streep and Roberts on board – and Andrea Riseborough being recently mentioned as well, Cooper’s casting is one more especially talented actor added to the growing list. Factor in the Pulitzer Prize winning source material (the play won the award for drama in 2008) and this project, which is expected to go into production this August, the film certainly has a lot going for it already. Thanks to Glenn for the heads-up.
