I know the premise of The Change-Up is a little corny but so are all body-switching comedies. What sets this comedy apart isn't even its R-rating but simply because you have two great leads in Ryan Reynolds and Jason Bateman. A new trailer has gone online and it has some raunchy humor but the best jokes are simply from Bateman and Reynolds playing off each other and how they react to their outlandish circumstances. I really dug what I saw when I went to the set and I've heard that the finished film is painfully funny.Hit the jump to check out the new red-band trailer. The film also stars Leslie Mann, Olivia Wilde, and Alan Arkin. The Change-Up opens August 5th.Trailer via Break.com.The Change-Up Exclusive Restricted Trailer - Watch more Movie TrailersHere's the official synopsis for The Change-Up:

Ryan Reynolds and Jason Bateman star in The Change-Up, from director David Dobkin (Wedding Crashers), writers Jon Lucas & Scott Moore (TheHangover) and producer Neal Moritz (Fast & Furious, Click). The R-rated comedy takes the traditional body-switching movie, ties it up tightly and throws it off a cliff.

Growing up together, Mitch (Reynolds) and Dave (Bateman) were inseparable best friends, but as the years have passed they’ve slowly drifted apart. While Dave is an overworked lawyer, husband and father of three, Mitch has remained a single, quasi-employed man-child who has never met a responsibility he liked. To Mitch, Dave has it all: beautiful wife Jamie (Leslie Mann), kids who adore him and a high-paying job at a prestigious law firm. To Dave, living Mitch’s stress free life without obligation or consequence would be a dream come true.

Following a drunken night out together, Mitch and Dave’s worlds are turned upside down when they wake up in each other’s bodies and proceed to freak the &*#@ out.

Despite the freedom from their normal routines and habits, the guys soon discover that each other’s lives are nowhere near as rosy as they once seemed. Further complicating matters are Dave’s sexy legal associate, Sabrina (Olivia Wilde), and Mitch’s estranged father (Alan Arkin). With time not on their side, Mitch and Dave comically struggle to avoid completely destroying each other’s lives before they can find a way to get their old ones back.
