Open Image ModalBefore playing, arguably, his most famous role in "Jurassic Park," Attenborough was an accomplished director and producer. He won two Oscars for "Ghandi"(1983) in the Best Director and Best Picture categories. After "Jurassic Park," Attenborough became very busy with everything but acting. While he did appear as Kris Kringle in the 1994 remake of "Miracle on 34th Street," he soon shied away from the camera to focus on things such as directing, becoming the head of various organizations including BAFTA, and opening an art exhibit filled with his vast collection of Pablo Picasso pieces. Attenborough died on Aug. 24, 2014, five days before his 91st birthday. (credit:Getty Images)

Since his infamous role, Ferrero hasn't been very busy in Hollywood, though he did appear in both "Heat" and "Get Shorty" in 1995. His most recent venture was actually a 2011 College Humor spoof of "Jurassic Park," in which he reprised his role as the ill-fated Gennaro. (credit:College Humor)

Open Image ModalThe dinosaurs in "Jurassic Park" were not the first creatures Steven Spielberg had a hand in creating. The legendary filmmaker directed the non-human-centric movies, "E.T.," "Jaws," and "Close Encounters of the Third Kind," before getting his hands on the movie's prehistoric monsters. As you most likely know, Spielberg continued his career as one of Hollywood's most well-respected and influential directors, writers, and producers after "Jurassic Park" wrapped. He went on to win Best Director Oscars for "Schindler's List" (1993) and "Saving Private Ryan" (1998). He was nominated in the same category for "Lincoln" at this year's Academy Awards. He is currently the producer of popular TV shows such as "Smash" and "Falling Skies." His next projects include producing the movies "Interstellar" and, of course, "Jurassic Park IV." (credit:AP)
