<P> In 1996, DiCaprio appeared opposite Claire Danes in Baz Luhrmann's film Romeo + Juliet, an abridged modernization of William Shakespeare's romantic tragedy of the same name, which retained the original Shakespearean dialogue . The project achieved a worldwide box office take of $147 million . </P> <P> Later that year, he starred in Jerry Zaks' family drama Marvin's Room, reuniting with Robert De Niro . Based on Scott McPherson's screenplay adaptation of his own 1991 stage play of the same name, the film revolves around two sisters, played by Meryl Streep and Diane Keaton, who are reunited through tragedy after 17 years of estrangement . DiCaprio portrayed Hank, Streep's character's troubled son, who has been committed to a mental asylum for setting fire to his mother's house . </P> <P> In 1997, DiCaprio starred in James Cameron's Titanic (1997) as twenty - year - old Jack Dawson, a penniless Wisconsin man who wins two tickets for the third - class on the ill - fated RMS Titanic . DiCaprio initially refused to portray the character but was eventually encouraged to pursue the role by Cameron, who strongly believed in his acting ability . Against expectations, the film went on to become the highest - grossing film to date (it was surpassed in 2010 by Cameron's film Avatar), grossing more than $1.843 billion in box - office receipts worldwide, and transformed DiCaprio into a commercial movie superstar, resulting in fan worship among teenage girls and young women in general that became known as "Leo - Mania". In May 1998, for example, his face appeared on the covers of at least four teen magazines, and three books about DiCaprio were among the top six paperbacks on The New York Times Best Seller list .

He was nominated for other high - profile awards, including a second Golden Globe nomination . Upon the success of Titanic, DiCaprio stated in 2000: "I have no connection with me during that whole Titanic phenomenon and what my face became around the world (...) I'll never reach that state of popularity again, and I don't expect to . It's not something I'm going to try to achieve either ." </P> <P> The following year, DiCaprio made a self - mocking cameo appearance in Woody Allen's caustic satire of the fame industry, Celebrity (1998). That year, he also starred in the dual roles of the villainous King Louis XIV and his secret, sympathetic twin brother Philippe in Randall Wallace's The Man in the Iron Mask, based on the same - titled 1939 film . Despite receiving a rather mixed to negative response, the film became a box office success, grossing US $180 million internationally . Though DiCaprio's performance was generally well - received, with Entertainment Weekly critic Owen Gleiberman writing that "the shockingly androgynous DiCaprio looks barely old enough to be playing anyone with hormones, but he's a fluid and instinctive actor, with the face of a mischievous angel," he was awarded a Golden Raspberry Award for Worst Screen Couple for both incarnations the following year . </P>
