Playing Johnny Depp's autistic kid brother in "What's Eating Gilbert Grape?", which earned him an Academy Award nomination for Best Supporting Actor in 1994.
Starring in a little movie called "Titanic."
Leonardo was cast for his first feature film, "Critters III," in 1991, and shortly after, he was invited to join the cast of the ABC sitcom "Growing Pains." Michael Caton-Jones then cast Leonardo in the much sought-after role of Tobias Wolff in his big-screen adaptation of Wolff's best-selling novel "This Boy's Life" in which Leonardo starred alongside Robert De Niro and Ellen Barkin.
In 1993, Swedish director Lasse Hallstrom cast Leonardo in the role of Arnie in the critically acclaimed film What's Eating Gilbert Grape?
In 1995, Leonardo played opposite Sharon Stone and Gene Hackman in Sam Raimi's "The Quick and the Dead," and the same year starred in the film adaptation of Jim Carroll's gritty autobiographical memoir "The Basketball Diaries."
As one half of the star-crossed lovers in Australian director Baz Luhrmann's screen adaptation of William Shakespeare's "Romeo + Juliet," Leonardo was paired with Claire Danes. He was also featured the same year as Meryl Streep's delinquent-to-the-point-of-criminal son in "Marvin's Room." In 1996, Leonardo starred in James Cameron's Academy Award winning film "Titanic" opposite Kate Winslet.
Next, he starred in "The Man in the Iron Mask." Leonardo owned the number one box-office position for the better part of 1998 with "Titanic" and virtually knocked himself out of the top spot with "The Man in the Iron Mask."
