Adam Brody got together with his costar, Debi Mazar, to talk about their upcoming film, Lovelace, which hits theaters on Aug. 9. We sat down with the pair to chat about the biopic of '70s porn star Linda Lovelace, and they revealed a few interesting tidbits concerning their porno scenes. Debi branded the making of the porn in the film, the "fun stuff," while Adam agreed that it was the "most lighthearted part of the film." The costars also dished about donning 1970s garb for the movie, which Adam used as a "great excuse to have a mustache." Watch the clip to hear more about their characters, the porn, and '70s styling, including growing hair in (private) places!
