 Reviewing his works of his early career, David Thomson of "The Guardian" called DiCaprio "a revelation" in "What's Eating Gilbert Grape", "very moving" in "This Boy's Life", "suitably desperate" in "The Basketball Diaries" and "a vital spark" in "Romeo + Juliet".DiCaprio refused an offer to do the film "Boogie Nights" (1997) to star alongside Kate Winslet in James Cameron's "Titanic" (1997) as members of different social classes who fall in love aboard RMS "Titanic" during its ill-fated maiden voyage.DiCaprio initially had doubts about playing the role, but was eventually encouraged to pursue the part by Cameron, who strongly believed in his acting ability.
