"I'm very excited, I can't say any more or I'll get in trouble," the actor laughed at the Hollywood premiere of his new movie Mercy, which he wrote and also stars in alongside his father James Caan and Alex O-Loughlin.
Scott explained he liked to explore relationships in the films he writes.
"I've always been fascinated with how relationships work and don't work, I've been asking advice on relationships since I was old enough to be in one," he confessed.
He also revealed his dad isn't afraid to tell him if he doesn't like the scripts he pens.
"He's honest with me and he tells me really what he thinks of the things I write. He's told me 'I hate this', but this one he really liked immediately and said 'I love it' and would play any part."
