There's many actors we're noticing who use butt doubles in movie scenes. Like, Dakota Johnson in "Fifty Shades of Grey"! We never knew she had a butt double and it was all due to her tattoos. Kit Harrington, who couldn't do his nude scene on "Game of Thrones" because of a broken ankle so she needed a butt double. Owen Wilson's booty is real in "You, Me and Dupree" but, directors chose to use a double. Mila Kunis didn't really get naked for Justin Timberlake in "Friends with Benefits", because she figured the sideboob was enough.
