Jason Bateman and Ryan Reynolds star in this fantasy comedy as two friends who swap bodies. Old friends Dave (Bateman) and Mitch (Reynolds) have wildly differing lifestyles, lawyer Dave is a family man, married to Jamie (Leslie Mann) with three kids, while eternal batchelor Mitch is happy to try and bed every woman he sees. While out on a rare drinking night together, the two friends, much the worse for wear, confess their admiration for each other's lives while standing in front of a magical fountain. The next morning, however, the pair are shocked when they wake to discover that they have swapped bodies. Initially intrigued by the novelty of their situation, it doesn't take long for Dave and Mitch to hanker after their old lives when events start to spiral out of control.
