This Movie is hilarious even though this same concept has been done before with Freaky Friday. But with a difference it's with two guys one being a bachelor and the other a married man. they both are thrown into worlds that they are not familiar with switching lives. from the very first scene you are able to tell what kind of movie it is with its crude humor they are forced to fight through the others lives until they are able to figure out how to switch back to their regular selves. this is a funny movie with a great comedic duo with Ryan Reynolds and Jason Bateman. also an appearance from Leslie Mann and Olivia Wilde to give this movie a little sexiness. overall this movie is a great movie and will have you laughing for days.
