Actor Zach Galifianakis showed off a slimmer and thinner frame at his upcoming movie premiere "Birdman" here. It was difficult to recognise him.

Galifianakis, best known for his role in "The Hangover" film franchise, could not be recognised after incredible weight loss recently, reports mirror.co.uk.

The 45-year-old actor wore a grey suit and has added long curly hair to his new look keeping the facial hair same.
