Hey there! so as most of us know, Chris Hemsworth wore a wig for the movie "Thor"
However, I just came across a site that showcased pictures from the "Avengers" NYC Premiere, and Chris does in fact have long hair tied in a little bun. I think that he may have used extensions in Avengers, but its still great seeing him as a longhair (and a handsome one at that). Check out the link:
Well, I hope he actually wore a wig for Avengers too, because if it was his hair, it was certainly bleached, which would be sad, given his beautiful hair color. Hiddleston was amazing as Loki, and I liked his hairstyle on the movie as well. But let's be honest here, Hulk absolutely stole the whole movie lol. Awesome flick, I would pay to watch it again without problems =)
For me it was Robert Downey Jr. who owned the movie hands down. But Chris had the best hair, obviously. Wig, extensions or whatever they did: the result looked nice.
Same site, different gallery. Beautiful hair, suits him well. One of my girlfriends always jokes of how she wants to marry Thor lol. I tottaly aprove her choice =)
