"It was my last day of filming Romeo + Juliet and we all went out to a bar afterwards," Rudd recalled on The Graham Norton Show. "I was riding to the place with Leo and he said, ‘I just got offered this movie and it's a big movie. It's a studio movie. It's Titanic."
As fate would have it, Rudd's father was a Titanic expert, which made him even more excited and eager to convince DiCaprio. "I said, ‘That's incredible,' and I knew a lot about Titanic because my dad would just talk about it," he continued. "And we just had a conversation about it and he was saying, ‘Oh, I don't know what I'll do.' And I remember saying, ‘You should do it!'"
