In an interview with GQ magazine, the film's director, James Cameron, recalled casting process for the film.
While Kate Winslet was casted early on, DiCaprio was a bit more difficult.
Before trying for a screen test, things became rocky, according to Cameron who said: “He came back a couple of days later, and I had the camera set up to record the video. He didn’t know he was going to test. He thought it was another meeting to meet Kate.”
The director claimed he refused to read with Winslet, which almost brought his audition for the huge role to an end.
DiCaprio ended up agreeing to do the screen test and secured the role.
