Famous comedian of Greek descent Zach Galifianakis left everyone speechless with his transformation at the premiere of his new film “Birdman” in New York. The popular “Hangover” star was practically unrecognizable after his dramatic weight loss.

Galifianakis started losing weight about a year ago after quitting drinking. In an interview with Conan O’Brien he explained the reasons that prompted him to do that.

“I stopped drinking and I just kind of put the weight off … I was having a lot of vodka with sausage … delicious but bad for you. I was getting into too much trouble with the drinking, so I just kind of stopped.”

At the premiere, which was his first public event in a year, Galifianakis also spoke to The Hollywood Reported about his experience as a celebrity.

“Being a celebrity is shit — it’s dumb and I’m not interested in it. I like to be an actor, and that’s it. The blurred lines are, I think manmade. I think celebrity is a manmade thing, it’s not innate in us, we have people telling us, ‘We should pay attention to these people,’ for all the wrong reasons, their personal lives and whatnot. … I’d rather just do my work and go home and watch Lifetime,” the talented comedian said.
