Rob Zombie is almost pulling a JJ Abrams card as to what his new project will be in 2009. There have been rumors for months about a film he's in the process of making titled Tyrannosaurus Rex. No plot has been released yet, but it is confirmed that T-Rex is indeed a biker. Some have mentioned his comic with Steve Niles simply titled Nails as being an adaption of the comic, but Zombie shut those rumors down and states it has nothing to do with it.
Below is a teaser poster / pic of Tyrannosaurus Rex.
