Imagine if Leonardo DiCaprio hadn’t landed the role that launched him to superstardom.

That nightmare almost became a reality back in the late 90s when director James Cameron was busy casting for the lead role of Jack Dawson.

Clueless star Jeremy Sisto, who played Elton in the 1995 chick flick, was also up for the part and recently revealed that he read with Kate Winslet for her screen test.

“That was one of the many, many jobs I didn’t get. It’s always fun to see a movie that you know really well and love with this alternate-universe person in there.

“So while I was a little embarrassed to reveal one of my many failures in life, at the same time I couldn’t deprive Titanic lovers of seeing that alternate universe,” Sisto told the Huffington Post.

“It was exciting to be a part of the process,” the actor, now 40, said. “To be involved in something that had that kind of scope — anything James Cameron does has this huge scope to it. He’s trying to push the limits on things. So I was just insanely inspired by it and a little heartbroken when the role didn’t come my way.”

Here’s Winslet’s first screen test . Sisto even read with three other actresses who were vying for the role of Rose.
