Lawyers representing the actor and ex-wife Diandra Douglas tangled in a New York court Tuesday over her claim that she's entitled to half his earnings from "Wall Street: Money Never Sleeps," set to open Sept. 24.

The dispute has featured accusations of avarice on both sides and an unusually detailed look at Hollywood-style divorce.

The couple's 23-year marriage ended in 2000. He's now married to Oscar-winning actress Catherine Zeta-Jones.

The former couple's multimillion-dollar divorce gives Diandra Douglas the right to share in proceeds from spinoffs and other projects related to work Michael Douglas did while they were married.

That, her camp says, should include director Oliver Stone's "Wall Street" follow-up, in which Michael Douglas reprises and updates his Oscar-winning role as Gordon Gekko, the take-no-prisoners financier whose declaration that "greed is good" became either a slogan or an epithet for the 1980s, depending on one's perspective.
