VIDEO : Andrew Garfield and Mel Gibson Talk 'Hacksaw Ridge'

The upcoming Mel Gibson-directed movie 'Hacksaw Ridge' tells the true story of Desmond Doss, an Army medic, Medal of Honor recipient, and conscientious objector. In a recent interview with ScreenRant, actor Andrew Garfield who portrays Doss and Gibson discussed the challenges they faced making this visceral war movie. Garfield explained, "You know, for me it was all about getting my body as strong, and as seemingly not strong, as possible. I needed to look as thin as Desmond was, but create this kind of inner, core strength. So that took some work." Gibson himself then added, "Everyone from the actors, to the extras, to the stunt guys, to the camera guys, to the special effects dudes, and everything came together. And these were big things, and so we were able to achieve a lot despite time constraints and budgetary constraints because of the talent and expertise of the fellows that I was working with."
