Michael Douglas is not what we would call a comic book guy. Sure, the veteran actor will next star in Peyton Reed's 'Ant-Man' (and he even grew some wild facial hair for the gig), but that doesn't mean that any of this comic book stuff is in his wheelhouse. He even thinks that 'Ant-Man' is about an ant. No, really.

Douglas hit 'The Late Show' last night to talk about his next part, as well as his upcoming appearance at San Diego Comic-Con, and David Letterman seemed a bit bewildered about the property. Is it very popular? Are there crazy fans? Will Michael Douglas be trampled at Comic-Con? What does Douglas really think about the film? Well, he certainly seems to be stuck on the "ant" thing.
