Scarlett Johansson has confessed she has a huge collection of comic books. The actress admitted she and husband Ryan Reynolds are keen to collect superheroes stories. "There is a lot of superhero stuff going on in our family right now," said Johansson. "We have quite a few stacks of comic books. We're in completely different universes but it's fun to get into that whole world together even if there is quite a stack of comic books taking up space." Scarlett will appear as the Black Widow in Iron Man 2 next year, while Reynolds has signed on to star in the Green Lantern and Deadpool.
