A former business associate of Hollywood actor Michael Douglas is suing the star for breach of contract.

Zack Norman - who appeared with Douglas in the 1984 movie Romancing the Stone - has launched a legal bid against the star in connection with a business deal.

Norman claims he was promised $1 million for his part in buying into a company with Douglas - but never received the money.

According to the lawsuit filed at Los Angeles County Superior Court on Thursday, Norman is seeking compensation.
