Renner admits doubles were employed throughout the shoot in an attempt to confuse the paparazzi who dogged the set in Canada.
He reveals, "People were sneaking on set trying to take our pictures. There were strategies to release our own photos so their photos become less valuable.
"There were a lot of things they (producers) tried to do, like hiring doubles for Brad, who would ride around on the motorcycle he would ride, so he could avoid the paparazzi.
"Brad tried to go out in public once in a while but it was nuts."
He adds, "I think if we sat down one-on-one and really spent time together that we'd have probably a ton in common. Yeah, what a grand guy. He's just a really, really cool kid."
