Actor Jim Carrey was originally tapped to play the lead role in Steven Spielberg's Jurassic Park, but he lost the part to Jeff Goldblum.

The funnyman was called in to audition for the role of mathematician Dr. Ian Malcolm in 1992, when producers were readying the dinosaur classic - however Carrey failed to win over the casting director, Janet Hirshenon.

In celebration of Jurassic Park's 20th anniversary, the cast and crew of the film sat down for a special interview with Entertainment Weekly, in which Hirshenon says, "I read the book and I thought of Jeff Goldblum right away. There were several other people we taped for the part, though. Jim Carrey had come in and he was terrific, too, but I think pretty quickly we all loved the idea of Jeff."

Actress Laura Dern also spoke about her casting process during the interview, revealing she only signed onto the project after appealing to her former co-star Nicolas Cage for advice.

She adds, "I was talking with Nicolas Cage, and we had just done Wild at Heart together, and I said to him, 'Nic, they want to put me on the phone with Steven Spielberg, but they want to talk to me about a dinosaur movie... And he was like, 'You are doing a dinosaur movie! No one can ever say no to a dinosaur movie!' I was like, 'Really?' And he's like, 'Are you kidding? It's a dream of my life to do a movie with dinosaurs!' So he was such an ­influence on me."
