The 31-year-old actor is about to star in The Fate of the Furious as Little Nobody.
In a new interview with Men’s Health, Scott has spoken about working in movies as Clint Eastwood’s son.
He revealed: “I came here to try and do something and nobody took me seriously.
“Everyone brushed me off, like, ‘you’re Clint Eastwood’s son, you’re not a real f**king actor.’”
Scott added: “Some people are still like that. I never thought I would last in this business, but it finally seems to be working out.”
The actor, who is the spitting image of his father in his youth, also spoke out about Clint’s tough love.
He continued: “My dad never gave me a cent. He made me work for everything. Man he was hard on me but it hardened me and gave me drive. My dad is a machine about exercise.
“He showed me how to lift when I was 14 or 15 – he gave me some advice, then left me to do it on my own.”
The 86-year-old Clint’s latest movie was Sully and star Tom Hanks revealed how the director would “treat his actors like horses” and “was intimidating as hell.”
On the Eastwood family code, Scott said: “Yeah, it’s actually a thing. Whatever you’re doing, you try to do your best at it every time.
“Just do it and then move on. You don’t ever backstab people or f**k someone over – you don’t have integrity if you do that.
“You show up on time for stuff. And you don’t bitch and complain about what you’re doing.”
Scott Eastwood’s full interview features in the May 2017 issue of Men’s Health, which is released today.
