Olivia Munn felt 'blindsided' by 'The Predator' casting registered sex offender

After learning that she shared a scene in The Predator with a registered sex offender, Olivia Munn took action and had the scene deleted from the film. In conversation with Ellen DeGeneres, Munn offered more details about learning the truth about Steven Wilder Striegel and about the difficulty of sharing uncomfortable facts in Hollywood.

Munn says she was "chastised" by the studio for telling her costars about Striegel, whose past she learned about from an acquaintance, and that she felt isolated from her costars after telling them even though it was to ensure they weren't blindsided by the news. She did not learn full details of Striegel's case until the L.A. Times published a story about it (including Munn's statement).

"The people who collude to keep people like this in positions of power, that's the real problem, the people who keep turning blind eyes," Munn says.

Striegel pleaded guilty in 2010 to having an online relationship with his "distant relative," a then-14-year-old girl (he maintains there was no physical contact, but the allegations say there was). The Predator hits theaters Sept. 14.
