We know that Ben Affleck, star of The Town and Good Will Hunting, will don the cape and cowl as Batman in Zack Snyder’s forthcoming Batman vs. Superman film. But what we don’t yet know is what the new Batmobile will be. Rumours this week may have given us a clearer idea what the new Dark Knight’s ride could look like, though. Unlike the military, utilitarian ‘Tumbler’ Batmobile from Christopher Nolan’s recent Dark Knight trilogy, Batman vs. Superman could be going back to the character’s roots. A source claiming to be close to the film project calling themselves Dr Detroit (sounds like one for Batman’s rogues gallery) has told Batman-On-film that the new Batmobile will be based on an old Cadillac. The doctor speculates that it may be modelled after a 1943 Cadillac convertible (pictured), as that’s the model which was used in the very first live action appearance of the Dark Knight, in the Batman television serial from the 1940s.
