First up from Variety is news that Miller will star in Chef, which follows a Steven Knight script that tells the story of a chef attempting to put together the best restaurant ever.  This project is not to be confused with Jon Favreau's recently released comedy of the same name, but not much more is available on the picture at this time.  This version of Chef will mark a reunion for Miller and Cooper, who recently wrapped on Clint Eastwood's American Sniper.

The Wrap reports that Barth will return for Ted 2 as Tami-Lynn, a cashier who fell for the title teddy bear and became his girlfriend.  Seth MacFarlane co-wrote the script with Alec Sulkin and Wellesley Wild and will once again direct the picture.  He also returns to voice the foul-mouthed bear alongside Mark Wahlberg's human character.  Amanda Seyfried will also be joining the sequel as the female lead with Mila Kunis only turning in a brief appearance.

The Wrap also has word on the latest addition to Tarzan.  Skarsgard plays the title role with Robbie as Jane Porter, and Waltz as Captain Rom.  Hounsou will play Chief Mbonga, described in this write-up as a "villainous warlord."  Ikhile's role remains undisclosed, except to say that it's a "key supporting role that will keep him on set for the majority of the shoot."  He just wrapped his role as a sailor in Ron Howard's Heart of the Sea, which opens March 13, 2015.

Finally, Deadline reports that Ortiz will join Southpaw with Jake GyllenhaalRachel McAdams, and Forest Whitaker.  Fuqua directs from Kurt Sutter's script.  Ortiz stars as "Ramone, a flyweight kid from the streets with real sparring potential" in a story that mirrors Ortiz's rags-to-riches tale.  Southpaw just began shooting in Pittsburgh.  You can see Ortiz on the big screen in The Expendables 3 on August 15th.
