'The Change-Up' Redband Trailer: Jason Bateman & Ryan Reynolds Get Dirty (VIDEO)

As the release date gets closer, the dirty gets dirtier.

"The Change-Up," the R-rated comedy that sees Jason Bateman's mild-mannered family man Dave switch bodies with stoner, semi-porn actor buddy Ryan Reynolds, hits theaters next week. And to prepare audiences for quite the shock, both in content and the stars who deliver the lines, Universal has unleashed a new red band trailer filled with a few of the dirtiest moments of the film.

No spoilers here, but expect some moments with naked pregnant women, inappropriate sexual remarks to law assistants and little girls alike, and plenty of words that would be cause for bleeps on broadcast TV.

In an interview with The Huffington Post, Bateman talked about playing against his usual type.

"I was like, wait a second, this is how they're gonna start?" he remembered saying to himself while reading the opening scene of the film. "All right, I'm ready, my knees are bent, I'm prepared for anything they're gonna throw me, and they didn't disappoint. It just kept coming."

Bateman was also just cast in "We're the Millers," a stoner comedy that's been long in the works.
