Jeremy Renner has claimed that his role as Hawkeye in The Avengers "wasn't the role he signed on to play".

The Bourne Legacy actor explained that his role as the superhero archer was a “big challenge” due to the lack of “backstory or understanding”.

Speaking to the Los Angeles Times, Renner said: "At the end of the day, 90% of the movie, I'm not the character I signed on to play. I'm literally in there for two minutes, and then all of a sudden…

"All I could really work on was the physical part of it all, because that didn't change. That was just the biggest challenge to overcome in playing the guy.

He added: "I was limited, you know what I mean? I was a terminator in a way. So yeah, fun stunts. But is there any sort of emotional content or thought process? No. That doesn't exist in that time [that he's hypnotized]. It happens to be for most of the movie."

The Bourne Legacy is in cinemas nationwide from tomorrow.
