Batman: Under the Red Hood trailer

MSN (?) has just debuted a new trailer for Batman: Under the Red Hood on its site. And while you may think the animated movie will be all about Batman tinkering with his red 67 Shelby Mustang it's actually about the Dark Knight finding himself being stalked by a mysterious criminal who seems to know all of his secrets. Scary.

Bruce Greenwood, Neil Patrick Harris, Jason Isaacs and Jensen Ackles lend their voices to the film. Check the trailer after the jump and the film hits your home theaters on July 27.
