What is Casting Couch? It’s the column that’s rounding up all the casting announcements the studios have released now that the buzz surrounding the Golden Globes has died down. They’ve been hoarding. Before his show on FX became such a well-respected thing, people thought of Louis CK mostly as being a stand-up comedian and not really as an actor, despite the fact that he’s shown up in a few small roles here and there. That might be about to change though, because not only does CK  star in Woody Allen’s upcoming movie, Blue Jasmine, but THR is reporting that he’s also in talks to join David O. Russell’s next project: that con-man movie starring Christian Bale, Bradley Cooper, Jeremy Renner, and Amy Adams that used to be called American Bullshit. If CK’s involvement becomes official, it will see him rubbing onscreen elbows with some of the biggest names in Hollywood, which is probably going to feel a little weird at first.
