Michael Douglas 'fears' for Cameron

Michael Douglas is extremely worried about what will happen to his son Cameron who is awaiting sentencing on drugs.

Shia LaBeouf says Michael Douglas is going through a personal "crisis" because of his son's pending drugs trial.

The 23-year-old actor stars with Michael in upcoming movie 'Wall Street: Money Never Sleeps' and has revealed the 65-year-old screen icon has been left "broken" by his son Cameron's legal woes.

He told German website Gala.de: "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."

Despite his family problems, Shia says Michael was a total professional on set.

The 'Transformers' actor admits he and director Oliver Stone wished they could have done more to support Michael.

Shia explained: "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."

Cameron is facing a possible 10 years in jail after pleading guilty in January to possession and dealing methamphetamine and cocaine from a Manhattan hotel last July.

Michael - who has two other children, Dylan, nine, and six-year-old Carys, with his wife Catherine Zeta-Jones - recently confessed he could have been a better father to his 31-year-old son

The 'Sentinel' star - whose father is screen legend Kirk Douglas - 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."

Cameron - whose mother is Michael's ex-wife Diandra Luker - will be sentenced on April 27.
