Will Arnett is the odd man out in "Teenage Mutant Ninja Turtles."
On the TV show that remains, for many fans, the definitive version of the characters so far, Vernon Fenwick is an adversary, a foil both for April O'Neil and for the Turtles themselves. In this new film incarnation, Fenwick is the cameraman who works most often with April O'Neil (Megan Fox), and he knows that she wants out of puff-piece features. He also knows how the game works, though, and he doesn't really seem to believe she's going to get her break. He's the cynical voice of reality.
