Way before Carrey started his Academy Award quest with movies such as Man On The Moon, The Majestic or the recent Eternal Sunshine, goofiness was what the man was about. Now, in this first 'Ace Ventura' movie, Carrey needs to do little more.
Carrey is Ace Ventura, a pet detective (duh) who's called in to find a stolen dolphin who's a mascot for a major football team (as one might expect: The Dolphins). While the police do their job to find it as well, Carrey proves his investigating skills while a young Courteney Cox helps along as Melissa Robinson, who works at the Dolphins (as what I don't remember. Oh well, who cares?).
The story provides some funny moments (the 'coming out' at the end, and in particular the scene in which Carrey snoops around the huge mansion of the cocky billionaire), but it's mostly Carrey's facial expressions and moves that saves this movie. Whenever you feel like the movie's getting more stupid by the minutes, he comes in and bags yet another scene. I'm gonna tell you, that guy is pretty damn funny.
