Quoting from one of the comments: FYI "Maniac is a short film by Shia Labeouf in tribute to the film Man Bites Dog by Benoit Poelvoorde (We can see the poster at 3:56) which is a Belgian movie and a french one by the language. It's black and white movie, where  a camera crew follows a serial killer/thief around as he exercise his craft. BTW, Man Bites Dog has a black, cynical humor which isn't in Maniac."
