Here's a preview of this week's new releases.
"Mama" is a thriller about the terrifying happenings that occur when two young sisters lose their parents and disappear on the same day. Years later they are found, but that's just where the story begins.
Arnold is back. In "The Last Stand," Schwarzenegger plays a lawman who has left Los Angeles for a more peaceful, small town existence. That's all shattered when a drug kingpin escapes federal custody.
