''Sinbad: Legend of the Seven Seas'' leads Brad Pitt and Catherine Zeta-Jones may finally get together in the flesh. Variety reports that the cartoon costars may wind up together in ''Mr. and Mrs. Smith,'' the comic thriller that was to have starred Pitt and Nicole Kidman as married assassins who learn they've been contracted to kill each other. Kidman may have to drop out because she'll still be too busy dodging another homicidal spouse in ''The Stepford Wives'' to be available for the fall ''Smith'' shoot.
According to Variety, director Doug Liman (''The Bourne Identity'') and the producers are scrambling to find another A-list actress to keep Pitt from bolting if Kidman can't make it, and Zeta-Jones is the top contender. Apparently, one 2003 Oscar-winning actress is as good as another. Besides, Zeta-Jones earned her credentials as a murderous wife in ''Chicago.'' And she's available, now that the deal has fallen through for her and her real-life husband to play partners in crime in ''Monkeyface.'' Guess ''Mr. and Mrs. Douglas'' just doesn't have the same ring.
