EXCLUSIVE: The follow-up to 2013’s Sylvester Stallone-Arnold Schwarzenegger actioner Escape Plan is firming up its cast. Jaime King has signed to play a female lead, Abigail Ross, in prison-break sequel Escape Plan 2, and Power’s  Curtis “50 Cent” Jackson is reprising his role as Hush from the first film.

Sources also confirm to Deadline that ex-MMA fighter Dave Bautista, who plays Drax in the Guardians of the Galaxy films and upcoming Avengers: Infinity War, will co-star with Stallone in the ensemble sequel. Plot details are under wraps.

Steven C. Miller is directing Escape Plan 2, and Miles Chapman — who scripted the first film — is writing the script. It’s a U.S.-China co-production with Emmett/Furla/Oasis and China’s Leomus Pictures. Randall Emmett, George Furla, Mark Canton, Zack Schiller and Robbie Brenner are returning to produce. Ted Fox, Mark Stewart, Barry Brooker and Stan Wertlieb will executive produce along with the Fyzz Facility’s Wayne Marc Godfrey and Robert Jones.
