Marvel star Chris Pratt warns of dangerous imposter

Marvel star Chris Pratt, who with his "Guardians of the Galaxy" colleagues shows up at the end of the recently released trailer for "Avengers: Infinity War," warns that someone pretending to be him is contacting fans trying to get phone numbers and other personal info. He's not amused.

"Please know, I find this behavior reprehensible," Pratt wrote in an Instagram post. "If I find out who it is I’ll have their account shut down and seriously would like to punch them right in the GD mouth. You hear that imposter!? Stop."
