Stuntman Scalped During Avengers Filming

Stuntman Jeremy Fitzgerald tells TMZ, his job was simple -- get hit with an arrow and fall 30 feet off a building ... but he caught his foot on the way down, and slammed his head into the brick ... leaving behind a freshly peeled slab of scalp.

But it could have been a LOT worse -- according to Jeremy, he narrowly missed a razor sharp rain gutter during the accident.
