I don�t know whether the directors, Rob Letterman (Shark Tale) and Conrad Vernon (Shrek 2), or the platoon of credited writers grew up on monster and alien flicks.
Monsters vs. Aliens — from DreamWorks Animation vets Rob Letterman (Shark Tale) and Conrad Vernon (Shrek 2) — isn’t trying to be deep: that’s just an unintended side effect (and one the audience can safely ignore, if it wants to) when you riff on just about every monster movie ever made and do it this cleverly, in ways that know you know way too much about the subject of cinematic apocalypse already.
In between scenes of mass destruction directors Rob Letterman (Shark Tale) and Conrad Vernon (Shrek 2), who are working from a script by committee, shell out the comedy with a similarly rapid-fire style, hurling sight gags and puns and throwaway one-liners as if they, too, are in 3-D.
Rob Letterman (writer/director of “Shark Tale”) and Conrad Vernon (director of “Shrek 2”) direct a script that took five writers to bring to the big screen and feels like it was haphazardly constructed like kids playing the story game on a playground.
The screenplay is credited to five people whose combined writing credentials include “The Simpsons,” “King of the Hill,” “The Larry Sanders Show,” and “Kung Fu Panda,” and the directors, Rob Letterman and Conrad Vernon, made “Shark Tale” and “Shrek 2,” respectively.
What directors Rob Letterman, who also wrote and directed “Shark Tale,” and Conrad Vernon, who directed “Shrek 2,” focus on in their first teaming is telling the story, which they both had a hand in creating, with Letterman also participating in the team sport that is the animation screenplay (credit also goes to Maya Forbes, Wally Wolodarsky, Jonathan Aibel and Glenn Berger).
