10. Dakota Johnson - Fifty Shades Darker
In order to make the steamy sex scenes in Fifty Shades Darker a little less stressful, Dakota Johnson decided to embark on a "pre-game ritual" ahead of shooting. Johnson claimed she would do a shot of whiskey and eat some mints between takes, while her screen lover Jamie Dornan would do push-ups. She resolutely concluded, "He does pushups and I just lay there and drink whiskey."
Considering the inherent intimacy involved in shooting a film of this sort, it's hardly surprising that Johnson turned to drink to calm herself, and the pressure of a rabid fanbase who holds the sordid source material as gospel surely can't help much.
Thankfully for Johnson, she filmed Fifty Shades Darker and the final movie, Fifty Shades Freed, back-to-back, so now she can get back to boozing for the sheer joy of it.
