I was on board with the Seven PsychoCats until i realized that cats stealing dogs is just ridiculous. Really took me out of it.
That said, take a look at this funny but NSFW Seven Psychopaths red band trailer, with all the actors replaced with cats:
Colin Farrell stars as a screenwriter who shadows his dognapping friends, played by Sam Rockwell and Christopher Walken (Wedding Crashers), for his next movie. Things go awry, however, when they accidentally steal a dog that belongs to a psychotic gangster, played by Woody Harrelson (The Hunger Games).
Abbie Cornish, Olga Kurylenko, Tom Waits, and Gabourey Sidibe also star. Seven Psychopaths premiers October 12, and unfortunately Seven PsychoCats isn't real, so you'll never get to see it.
