Paul Rudd gave Leo some career advice

Paul Rudd played Dave Paris, the governor's son and Juliet's fiancé.

On set, Rudd helped convince DiCaprio to take the part of Jack Dawson in ‘Titanic’ - a movie that catapulted him to A-list status.

While they were on their way to a bar following Rudd’s last day of filming, DiCaprio casually told his co-star about the upcoming disaster epic.

Rudd recalled: "He was saying, 'Well, I don't know what I'll do,' and I remember saying, 'You should do it.'"
