Summit's upcoming thriller Gone has added a few more actors to the payroll. Jennifer Carpenter "Dexter"), Emily Wickersham (I Am Number Four), and Wes Bentley (bad movies) have joined the cast.

The film revolves around a character played by Amanda Seyfried. She returns home one night to find that her sister is missing. She is convinced that the same serial killer who abducted her years prior is behind the disappearance. However, when the police don't believe her, she sets out to find her sister on her own.

That serial killer doesn't know what's about to hit them. If there's one thing a methodical killing machine who plans every step in explicit detail isn't ready for, its a 98 lb. girl barely out of state school. (Variety)
