The Change-Up is a 2011 American fantasy romantic comedy produced and directed by David Dobkin, and written by Jon Lucas and Scott Moore.

In Atlanta, Dave Lockwood is married with three children, while his best friend Mitch Planko is single and at his sexual prime.

The next morning, Mitch and Dave realize they have “switched bodies.” Returning to the park to wish for their lives back, they discover the fountain has been removed for restoration.

As Dave's firm is about to agree, Mitch observes that the other representatives have not yet left, and compares the negotiations to sex and porn.

She tells him she is going to have sex with him, but when he sees her tattoo of a many-spotted skipperling – his daughter's favorite butterfly – his focus returns to his family, and is determined to leave.

At the gala, Dave's boss delivers a speech about his accomplishments and love for his family, filling Mitch with guilt.

In addition, Sydney Rouviere and Lauren and Luke Bain portray Dave and Jamie's three children, Cara, Sarah, and Peter, respectively.
