To prepare for his role as a stoner Ned in the new comedy film "Our Idiot Brother," Paul Rudd had to think on his feet.
"It was the first time I've worn Crocs," he told OnTheRedCarpet.com co-host Rachel Smith at the film's premiere, referring to the popular and colorful plastic footwear. "But I knew, as soon as I read the script, it's like, 'I think Crocs' and short shorts and tank tops. And having a beard is always great and I used to have very, very long hair. So that was kind of a nice walk down memory lane."
"Our Idiot Brother" stars Rudd as an idealist stoner who invades the lives of his three sisters, played by Elizabeth Banks, Emily Mortimer and Zooey Deschanel. (Check out photos from the film's Hollywood premiere here).
"I loved the script, I love the character and I think how often do you get to play somebody that has absolutely no irony, he's not judgmental in any way," Rudd said. "He's not jaded and he has made a very specific conscious choice to live his life this way and refuses to be beat up emotionally and every other way when it doesn't always work out for him."
Rudd, who has acted in huge comedy hits like "The 40-year-old Virgin" and "Clueless," added that he admired his "Our Idiot Brother" character.
"I thought, that's an incredibly noble person and that would be a fun way to spend the summer," he said. "I think apart from the physical look, there's definitely a different character."
"I've seen Paul in this light I think he's just bringing it to the rest of the movie-going public," added Rudd's co-star, Elizabeth Banks.
Rudd jokingly compared his role to the character Daniel Day-Lewis played in the 1989 film "My Left Foot."
"It's not Christy Brown, but we have similar beards," Rudd said.Check out the trailer for "Our Idiot Brother" below.
