Zach Galifianakis was unrecognizable at 2015 SAG Awards

Zach Galifianakis appears to have lost even more weight. 'The Hangover' actor looked almost unrecognizable at the 2015 SAG Awards.

During the opening of the show, Zach joined stars like Robert Duvall and Jennifer Aniston in sharing their stories of becoming actors. When Zach turned to the camera, he jokingly questioned: "I'm Zach Galifianakis ... I'm an actor?"

According to E!, Zach joked about his weight loss at the "Birdman" premiere in October -- and back in May 2013, the actor opened up to Conan O'Brien about it, saying:

"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."
