He looks like he is on roofies. Anyway, hope the next (last) Hangover movie would be a fitting end.

Handsome guy

Just by seeing the pic was so difficult, his voice helped me to recognize him. how can people change that much! surprising

I think it's hot. Guess I'm the only one :/

Every guy looks better in a beard IMHO.

Man, Ewan MacGregor really let himself go.

i saw zach at a restauraunt in asheville! we made eye contact a few times but then i realized it was only because i was staring at him :(

Seth has a mustache!!

That's not Zach, that's his twin Seth.

he only looks normal if i put my hand over the lower half of his face

I'm sorry but I honestly don't believe this is him.

…..byoiiiing.

sacreligious!!!

Beard/No beard, fat/skinny, Current/past…In MY opinion Zach Galifianakis is one super fine lookin' bro. I'd marry(hit)that.

He was actually really good looking when he was younger.

I bet you think all white people look alike.

Looks like Dave Coulier. Uncle Joey from Full House

without a beard and not fat.
