Actor: Jim Carrey
Films: Ace Ventura: Pet Detective (1994), Ace Ventura: When Nature Calls (1995)
Ace Ventura is, err, a Pet Detective. His dedication to animals and knowledge of their ways is astounding and he easily leaves Richard Attenborough, Bill Oddie and Steve Irwin in the shade when it comes to using them to solve insignificant crimes. Had he been out of detective work and looking for another organisation, his love of all things breathing would undoubtedly have caused him to be snapped up as ambassador for PETA in a second.
OK, so most people accept that Ace Ventura: Pet Detective and Ace Ventura: When Nature Calls aren't the best films in the world, but it would be fair to say that some would argue that they are the funniest. Ace Ventura is Jim Carrey at his stupid best, pulling faces like never before and genuinely being funny without the creepy dark undertone that marred his later films.
It is this stupidity that puts most people off Carrey. When he's not practising for Celebrity Gurner of the Year 1995, he's talking jibberish or peeping out from the rear of a rhinoceros. However, based on this, you do know what you can expect from almost every Jim Carrey film.
