Matthew McConaughey Auditioned for a Role in "Titanic"

But in the end, Leonardo DiCaprio landed the role of Jack, and it made him a superstar. How did that happen?

As Puck reports, McConaughey auditioned alongside Kate Winslet, according to film producer Jon Landau in his book. The filmmakers wanted to test whether they'd have on-screen "chemistry." The actress was happy with her potential co-star, but James Cameron wasn't impressed.

The director didn't like the actor's Southern accent. But when Cameron asked Matthew to run the scene again differently, he confidently said "no," explaining that he'd already done it well enough. The filmmaker immediately passed on him.

Actor Matthew McConaughey — Matthew McConaughey could have starred in Titanic

According to Landau, McConaughey was already a well-known and in-demand actor by 1997, but none of that mattered to Cameron, who was put off by the artist's unwillingness to follow his direction. The zoomboola.com editorial team wants to note that imagining McConaughey as Jack now feels impossible – and that's probably for the best. The actor went his own way, clearing the path for DiCaprio.
