Jason Bateman 'felt uncomfortable swearing in The Change-Up'

Jason Bateman has said that he found it difficult to swear in front of his 6-year-old co-star Sydney Rouviere in The Change-Up.

The former Arrested Development star explained that while it was nice to let his wild side loose in the R-rated comedy, he felt guilty for having to curse in front of the young actress playing his daughter in the film.

Bateman told the Huffington Post: "You spend 20 minutes apologising to her and her mother and another 20 afterward, and then while you're shooting, you just kind of let it fly."

"She was a great little actress, she got it, she understood the jokes."

Bateman went on to reveal that the movie, which also stars Ryan Reynolds, has a degree of warmth to it that he promised will not compromise the film's appeal.

"There's a lot of heart in it without diluting the R [rating], an extra later that's not obligated, that's not annoying, not treacly crap," Bateman said. "It sort of fits, there's a very realistic tone that runs all the way through this movie."

The Change-Up centers on two men who switch lives after urinating in a magical fountain.

The film also stars Leslie Mann and Olivia Wilde. It is scheduled to be released in the US on August 5 and in the UK on September 16.
