Dennis Hopper got the chance to watch his son Henry in his first acting role before he died last year after director Gus Van Sant rushed the movie veteran a rough cut.

The Easy Rider star was dying of cancer and Van Sant knew the actor didn't have long left, so he handed Hopper a reel featuring Henry's debut in Restless.

The director tells The Hollywood Reporter, "He said that Henry reminded him of himself in Rebel Without a Cause.

"Dennis was very happy and relieved that Henry, who set out to become a painter, was acting."

Restless will debut at the Toronto International Film Festival in Canada.
