According to Jezebel, a Bradley Cooper look-alike has been snapped partying at the 2016 Sundance Film Festival. The issue with this guy is that he's sneaking into parties and fooling people into thinking that he is actually the frequent Jennifer Lawrence collaborator.
Between the beanie and the likelihood that a million people were annoying the bouncers, it's understandable this guy passed as Bradley Cooper. If Cooper had any films showing at Sundance or were actually in Utah, this guy might have a better chance of keeping his ruse going. However, Cooper is in New York, at least for now.
Looks like the Cooposer is going to have suffer and wait in line like the rest of the non-celebs at Sundance.
