When Matt Katzenbach decided to crash Sundance 2016 along with his entourage, he asked for Vanity Fair's tips on how to look and act like Bradley Cooper.

Getting the tips, they decided to put the look and act like Bradley Cooper to the test.

They got tips on what to wear, how to interact with people in the party, names to mention and even some moves.

And as the night went on, it seems that they were successful in pretending to be Bradley Cooper. People were noticing him and was even asking for a picture.

It was a night and it went by without anyone noticing that it was not the actor.

What's even more outrageous is that Matt has an identical twin brother Scott who looks exactly like Bradley too.
