Ryan Reynolds has said it was a "dream come true" to work with old friend Jason Bateman in The Change-Up.
The two actors, who both appeared in 2006's Smokin' Aces, reunite in the Freaky Friday-style comedy, which sees a bachelor, played by Reynolds, wake up one morning in the body of lawyer and devoted husband and father Dave, played by Bateman.
Jason said at the movie's LA premiere: "We were friends before this and we always looked for the perfect thing to do together and this really qualifies as that, so we were lucky to get it."
Ryan added: "I've known him for about 15 years, we actually did a film together but we didn't get to work together so this is like a dream come true."
Their co-star Olivia Wilde said the atmosphere on the set of the film, written by the screenwriters of The Hangover, was definitely fun.
And the Tron: Legacy actress said the cast's appreciation for the script made them work extra hard.
"It was absolutely insanely hilarious and fun," the actress said at the film's Los Angeles premiere.
"I think we all just loved the script so we got to the set and just wanted to make the most of it, and to do it justice."
But love for the script didn't stop the film's stars improvising, with Olivia particularly proud of one unscripted scene, cryptically hinting: "It was something I didn't think would get in, and it got in, and it involves tattoos."
