Actor-musician Guy Pearce felt apprehensive about starring opposite Robert Downey Jr in "Iron Man 3" because he feared the superstar would be difficult to work with.
Pearce, 45, said he had reservations about dealing with Downey Jr on the set of the blockbuster but soon he realised his concerns were unfounded, reported Contactmusic.
"I was a bit nervous that he might have been a bit of a firecracker and he was never going to listen to anything anyone said. I thought, 'Wow, this guy's a genius, he's not even going to notice I'm there.' But it was the complete opposite.
"And it's not like he's sold out and he's playing some schlocky (sic) superhero and he's doing it badly. He's brought this incredible skill to a role that somebody else might be bland with," he said.
