Anastasia Steele (Dakota Johnson) doesn't quite know what's in store for her before she steps into Christian Grey's (Jamie Dornan) "play room" in the new trailer for Fifty Shades of Grey that aired during Super Bowl XLIX. While we don't see what happens after she enters the "play room" quite yet, Anastasia's naivete is put on display in this footage, since she believes this is simply a room with his "XBox and stuff."

Fifty Shades of Grey is the hotly anticipated film adaptation of the bestselling book that has become a global phenomenon. Since its release, the "Fifty Shades" trilogy has been translated into 51 languages worldwide and sold more than 100 million copies in e-book and print-making it one of the biggest and fastest-selling book series ever. Stepping into the roles of Christian Grey and Anastasia Steele, who have become iconic to millions of readers, are Jamie Dornan and Dakota Johnson.

Joining Dornan and Johnson in the cast are Luke Grimes as Elliot, Christian's brother; Victor Rasuk as José, Anastasia's close friend; Eloise Mumford as Kate, Anastasia's best friend and roommate; Marcia Gay Harden as Dr. Grace Trevelyan Grey, Christian's mother; Rita Ora as Mia, Christian's sister; Max Martini as Taylor, Christian's bodyguard; Callum Keith Rennie as Ray, Anastasia's stepfather; Jennifer Ehle as Carla, Anastasia's mother; and Dylan Neal as Bob, Carla's husband.
