VIDEO : Ben Affleck: Director And Star Of 'Marathon' Sex Scenes With Sienna Miller

Ben Affleck unintentionally earned quite a reputation on the set of 'Live by Night'.
Affleck plays notorious gangster Joe Coughlin in the crime drama, and Sienna Miller co-stars an Irish vixen, Emma Gould.
During a "marathon" of sex scenes, director Ben had to give Miller some acting notes, too, all while making her feel comfortable in an uncomfortable situation. Awkward!
Fortunately, Miller told E! News the scenes usually ended in tears--of laughter!
