Monsters vs Aliens is directed by DreamWorks filmmakers Rob Letterman (of Shark Tale previously) and Conrad Vernon (of Shrek 2 previously). Oddly, DreamWorks never revealed who the writers were, which makes me a bit worried that this was a studio-wide collaboration. Paramount will debut Monsters vs Aliens in both IMAX 3D and regular theaters on March 27th, 2009 next year.
