James Cameron’s blockbuster of an icebreaker movie, Titanic, was released in 1997, making it 23 years old. Coincidentally, that’s how old Leonardo DiCaprio was when he starred in it: he was 23. And his co-star, Kate Winslet, was 22. And now, all these years later, DiCaprio, in particular, is on top of the world… though both Winslet and Cameron have done just fine, thanks.
