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. 84 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.  More than 200 fans contacted the Academy of Motion Picture Arts and Sciences to protest him not being nominated for the 70th Academy Awards.  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. "
