Douglas is being sued by his ex-wife, Diandra Douglas, who is claiming that she is entitled to 50 percent of his earnings from the upcoming 'Wall Street: Money Never Sleeps' as part of her divorce settlement from the actor,

If it seems strange that Diandra would be seeking her share of her ex-husband's salary for a movie he made a decade after their divorce was finalized ... well, it is. The suit appears to hinge on a clause in Michael and Diandra's divorce settlement that entitles her to 50 percent of any earnings Michael receives from any movies he did -- including residuals, merchandising and ancillary rights -- during their 23-year marriage. According to Diandra's lawyers, that provision includes any "spinoffs" of Douglas' movies.
