What Happens in Vegas is the kind of terrible mistake performers as big as Cameron Diaz and Ashton Kutcher usually make at the beginning of their careers, when they're anxious to break into the movies, or at the end, when they're struggling for a comeback.
It's a screwed-up screwball farce about a slacker (Kutcher) and a go-getter (Diaz) who meet and get married one drunken night in Las Vegas. They win a $3 million jackpot with her quarter and his pull on a one-armed bandit and are sentenced to "six months hard marriage" when they try to get an annulment and sue each other for the money. It will have Diaz fans wistfully recalling There's Something About Mary and Kutcher fans who lined up for Guess Who wondering, instead, "Why?"
What Happens in Vegas (20th Century Fox) Starring Cameron Diaz, Ashton Kutcher, Rob Corddry, Lake Bell. Directed by Tom Vaughan. Rated PG-13 for language, crude humor and sexual content. Time 99 minutes.
