Co-stars Theron, David Oyelowo and Sharlto Copley provide the proper pronunciations of their names -- and you've probably been saying 'Theron' wrong this whole time. 'Gringo' is in theaters now.
Olyelowo and Joel Edgerton co-star, along with Amanda Seyfried and Charlize Theron, in the dark comedy set south of the border. 'Gringo' opens in theaters on March 9.
