John Gallagher Jr., Tony Goldwyn, Adria Arjona, Michael Rooker and John C. McGinley are among those already aboard.
Del Rio will next appear in Undraftedwith Chace Crawford and Aaron Tveit.
The 31-year-old Puerto Rican actress has joined the cast of the MGM action horror pic The Belko Experiment.
Written and produced by Guardians of the Galaxydirector James Gunn, the film is set to begin production next month in Bogota with director Greg McLean.
Diaz will play Dany Wilkins, the new girl at Belko Corporation. It’s her first day working in the building, and she really couldn’t have chosen a worst first day, since this is the day the employees are forced to either kill each one other or be killed.
Diaz starred in 2014 Sundance hit Fruitvale Station, and her recent credits also include HBO’s Girls and the features X/Yand The Cobbler.
