Based on Greg Pak's comic-book storyline (Incredible Hulk issues #92 to #105), the movie begins with the Illuminati (a secret group of superheroes that includes Iron Man and Professor X) sentencing the Hulk to exile on a deserted planet because the big, green guy has become a danger to Earth. While in outer space, Hulk does what Hulk does best -- gets angry -- and causes his rocket to crash land on the vicious planet of Sakaar, where he is captured and eventually becomes a triumphant gladiator.
Yet this Hulk has more on his mind than just smashing baddies. "No one has ever seen the Hulk like this before," supervising director Frank Paur told EW. "What happens if the Hulk doesn't change back into Bruce Banner? Who is the Hulk then? That's where we start playing with the idea that the Hulk is a thinking, rational being. We start to get into the Hulk's psyche -- what makes him tick?" You'll find out when Planet Hulk debuts on DVD in February 2010.
