Dueling Movies: Deliberately averted by the producers. Beastly was originally scheduled to be released in 2010 around the same time as Charlie St. Cloud, but since Vanessa Hudgens and Zac Efron were still dating, Beastly was moved up to avoid competition between the then-couple. In hindsight, this might have been a moot point, as neither movie appears to have been very successful.
Dyeing for Your Art: Alex Pettyfer shaved his head bald. As his hair had been a security blanket for him, it acted as Enforced Method Acting to understand Kyle's transformation. He also put on about fifteen pounds of muscle.
Missing Trailer Scene: Blink-and-you'll-miss-em clips of Lindy hanging on Hunter and him giving her a piggy-back ride, him standing on top of the Manhattan Bridge, Hunter running through a park, Kyle rubbing Lindy's lips with his thumb, Hunter catching Lindy as she jumps off a wall, and Lindy telling Hunter he's the most beautiful man she's ever met (the angle and the fact that she's crying suggests it might have been the scene from the book where he gets shot).
