Wish they had done it for Renner in the Avengers movie. He had on at least 3 forearm supports in almost every shot. I have seen a clip somewhere (that I cannot find) that showed Jennifer Lawrence vs. Renner on a Japanese talk show. Renner missed a lot and Lawrence was dead-on.

Glad Reedus got training. (And yes, I do understand these are different types of bows. I was just commenting on the fact that some actors act it and some actors do it).
