Little Ashes (2008)
In the movie Little Ashes, actor Robert Pattinson has a solo scene where he pleasures himself. And according to Pattinson himself, “faking it” just didn’t cut it — so he took matters into his own hands. Umm, literally.
Pattinson masturbated to completion in real life during the scene, and later joked that “My hand job face is recorded for eternity.” Sure is, Rob.
