Hi, I'm pretty new here but I found this on google and thought I'd give it a shot. I wanna know what the movie is called when there's groups (Like.. Killer groups) Who gets hired to take a mans head. And the police protects him.

I recall one of the groups being circus freaks and shooting clowns through a cannon. And they all wanna kill this man cause he got a huge price on his head. So they hire tons of "headhunters" i guess.
