Jeremy Renner admits he has ''zero idea'' what 'The Avengers' film is going to look like and concedes he may even be an ''extra''.
The actor - who portrays bow and arrow expert Hawkeye in the eagerly anticipated Marvel comic adaptation - admits there is so much "happening" in the Joss Whedon-directed project that he does not even know how big his role is in the picture.
He said: "It's immense. But, with that, you pass the baton. You get to work with very few of them 'cause everybody's got their own thing going on.
"Someone's in the air, flying around. I'm on the ground, shooting a bow and arrow. There are a lot of things happening. I have no idea what that movie looks like. Zero idea. Most of the time, I have a good idea of how it's going to turn out because I've seen so much of it, but I have no idea. I feel like I might be an extra in it. I'm not sure."
Jeremy originally appeared as the character in 'Thor' - which stars fellow 'Avengers' actors Chris Hemsworth and Tom Hiddleston - but he reveals he knows very little about his part because the role was so small.
He added to Collider.com: "In' Thor', I had to just stand in a bucket and hold my bow and arrow. What's the character? I have no idea. I was thrown into that very quickly, so it was like, 'Am I trapping myself?' It's a little strange. I don't know if it's a good thing. I don't think I'd go about it, normally, that way. It's certainly a different way to go about taking on a role."
