WATCH: HBO Looks at Why Killers Kill in Crazy, Not Insane Trailer

  • What makes a killer kill? HBO is set to tackle that question in the new documentary Crazy, Not Insane.

    "I think any one of us, myself included, could kill," says Dr. Dorothy Otnow Lewis, a psychiatrist who has studied murderers at length says in the just-released trailer. "Don't you ever wonder why you don't murder?" 

    Crazy, Not Insane premieres November 18 at 9:00 PM ET on HBO.

    Andy Hunsaker has a head full of sitcom gags and nerd-genre lore, and can be followed @AndyHunsaker if you're into that sort of thing.
