Trivia: A subtle reference to this film's 3D format: In Max's box, Trevor finds a pocket stereoscope, which are funky looking glasses that create the illusion of a three-dimensional image from two-dimensional photographs. It was invented by Sir Charles Wheatstone in 1840.
Trivia: Stan Lee (Stanley Martin Lieber), the original creator of this comic book hero, has his usual cameo role in this movie. He's the guy who drinks the gamma contaminated soda from the fridge.
