LaBeouf, 23, who is Michael's co-star in the upcoming flick Wall Street: Money Never Sleeps, has disclosed the 65-year-old actor is troubled over son Cameron's legal wrangles.
"I met a broken man, not Michael Douglas the celebrity. This man suffers; he's going through a crisis. He fears for his son. Cameron is facing a prison sentence because of his drug dealing. When I worked with Michael, he would visit his son in prison before he arrived at the set. It was really difficult for him," News.com.au quoted LaBeouf, as telling German website Gala.de.
LaBeouf also said both he and director Oliver Stone wished they could have done more to support Michael. "Oliver was really sensitive, but he had to finish his film at the same time. That's why there wasn't a lot of time left to comfort Michael. That was tough," he said.
Cameron, 31, may face an imprisonment of up to 10 years after he pleading guilty in January to possession and dealing with drugs from a Manhattan hotel last July. Michael, the son of screen icon Kirk Douglas, had recently said he could have been a better father to Cameron.
He said: "My priorities were very similar to my father's. Career first. The history of second-generation actors isn't great in our industry. It's kind of a tragic road, actually. Anybody who has a relative or child in substance abuse has some idea of what this feels like. This is one of those worst-case scenarios. It will ultimately be a painful lesson."
