The Change-Up is a 2011 American body-swap comedy film produced and directed by David Dobkin, written by Jon Lucas and Scott Moore, and starring Ryan Reynolds and Jason Bateman. The film was released on August 5, 2011 in North America by Universal Pictures.
Growing up together, Mitch Planko and Dave Lockwood (Ryan Reynolds and Jason Bateman) were two inseparable best friends, but as the years have passed, they have slowly drifted apart. Dave is an overworked lawyer, husband and father of three children and Mitch is a single, quasi-employed man-child who has never met a responsibility he liked. To Mitch, Dave has it all: his beautiful wife Jamie (Leslie Mann), three children 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 pee in a wishing fountain, and remark that they wish they had each others lives. Their worlds are turned upside down when they wake up in each other's bodies and proceed to freak 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 McArdle (Olivia Wilde) and Mitch's estranged father, Mitch, Sr. (Alan Arkin). With time not on their side, Mitch and Dave struggle to avoid completely destroying each other's lives before they can find a way to get their old ones back.
The film was shot in Atlanta, Georgia from October 2010 to January 2011, which is also the film's setting. There were open castings at Turner Field and other venues in Atlanta. Several of the bar scenes were shot on location at a bar called Joe's on Juniper, in midtown Atlanta. Despite being set in the summertime, production continued during a major winter storm that briefly crippled the city in January, leaving Peachtree and other streets covered in snow and ice and nearly preventing the governor's inauguration. Reynolds complimented the city in an interview on The Tonight Show with Jay Leno, but joked that he thought the city "was trying to kill" him because of several unrelated incidents on the set and in his personal life that happened to occur during production.
During an interview on Jimmy Kimmel Live, Olivia Wilde refused to appear naked or take most of her clothes off. She used a body double for some shots and wore pasties for close-up and upper shots. Leslie Mann have also followed this technique while other actresses used prosthetics.
