CHUD reports that according to their sources, 'The Fallen' of the upcoming "Transformers" sequel's new subtitle 'Revenge of the Fallen' is actually a character from comic book continuity.

More specifically he's an ancient Transformer who's essentially the Devil of their mythology as in one of the original good 13 Transformers who turned on his fellow beings and was cast down. Now he's 'The Fallen', a being of power, darkness, and absolute dedication to Unicron - the twin brother and arch-enemy of the Transformers creator Primus who was sealed with Fallen into extradimensional limbo.

New Transformers in this film include remote-control truck 'Wheels' (blurry photos), three Can-Am Spyder motorbikes become 'Arcee', a beat up old ice cream truck which becomes 'The Twins', the 2008 Pontiac Solstice which becomes 'Jazz', and an Autobot based on the Chevrolet Beat concept car.

Over the weekend John Turturro, Megan Fox, and Shia Lebeouf were all part of a scene set around a SR-71 Blackbird at the Steven F. Udvar-Hazy Center in Virginia which transforms into 'Jetfire' during the scene apparently.

Shooting gets underway in Philadelphia this week, making notable use of the University of Pennsylvania for college scenes with Sam (Shia LaBeouf), a local power station, and the Eastern State Penitentiary (now a museum) which will be used for a possible jail break scene.
