I haven't seen or dreamt about The Avengers, so this post comes to you without the taint of Whedon, which as J says makes everything great/hot.
Most of my Hemsworth knowledge comes from a Foxtel ad, where he walks around some house encountering characters from TV and looking hot.
At one point, a horse becomes involved.
So obviously, hot.
Also, as you can see, he is wearing a gentleman's bun in his hair, which is almost impossible to do and look hot. That he even remains a contender with that bun makes me think he might actually be quite an advanced level of hot.
It pains me that we don't just know though. God I wish this hunk recession would end. I had a dream about Channing Tatum the other night. Channing Tatum, you guys. We need a real hunk.
