Production is underway on Peter Farrelly’s (pictured) Untitled Comedy portmanteau boasting an all-star cast including Hugh Jackman and Kate Winslet.

The growing cast includes Banks, Gerard Butler, Kieran Culkin, Hugh Jackman, Johnny Knoxville, Christopher Mintz-Plasse, Chloe Moretz, Liev Schreiber, Sean William Scott, Tony Shalhoub, Emma Stone, Matt Walsh, Patrick Warburton, Naomi Watts, and Kate Winslet.

Farrelly, Brett Ratner, Elizabeth Banks, Bob Odenkirk, and Griffin Dunne have already completed their segments and additional directors will be announced shortly.

Relativity boarded the project as co-financier and co-producer in January and will arrange distribution through a studio partner. The company will handle international distribution through its expanding network.

Ryan Kavanaugh is producing alongside Farrelly, Charles Wessler and GreeneStreet Films’ John Penotti. GreeneStreet’s Tim Williams and Tucker Tooley of Relativity Media serve as executive producers and Witness Protection Films is also on board as a production company partner.

The producers envision a series of sketch comedies in the vein of the 1970s hits Kentucky Fried Movie and Groove Tube.

“Relativity has been the perfect partner through the extraordinarily complicated process of putting this movie together,” Farrelly said. “We are thrilled to be underway.”
