Shia LaBeouf was seriously concerned for Michael Douglas when they met on the set of the Wall Street sequel - describing the veteran actor as a "broken man" following revelations about his son's legal problems.
Cameron Douglas was arrested last August (09) following a drugs raid on his room at a New York City hotel. He pleaded guilty to one count of possession with intent to distribute a controlled substance and one count of possession of heroin, and will remain behind bars until he is handed his sentence in April (10).
At a recent bail hearing, Cameron's lawyers blamed his superstar father for his problems - insisting the 31 year old turned to drugs because he was "hurt" by Douglas' celebrity status and his "difficult upbringing".
LaBeouf recently began working with Douglas on upcoming movie, Wall Street: Money Never Sleeps and admits his 65-year-old co-star has been suffering greatly because of Cameron's ongoing troubles.
He tells German website, "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."
And the Transformers star reveals director Oliver Stone tried to accommodate Douglas' situation - but found it difficult because of the tight filming schedule.
He adds, "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."
