The Internet Movie Database is a good source of information about this kind of thing, although their facts are not always completely accurate. According to the IMDB Jim Carrey has appeared in 29 movies, not including made-for-TV movies, with 5 more movies in various stages of production. 17 of these have been made since his breakthrough role in Ace Ventura: Pet Detective. http://www.imdb.com/name/nm0000120/

I thought it was 17 not counting him in In Living Color.
