SANTA MONICA, Calif. (AP) _ Jurors decided producer Mace Neufeld should get $2 million-plus in a breach-of-contract suit against ''Cagney & Lacey'' producer Barney Rosenzweig and Orion Pictures Corp.

After a 16-day trial, the Superior Court jury on Wednesday assessed Rosenzweig $1,250,000 and Orion $758,978, and added 7 percent annual interest, which could come to $500,000.

Superior Court Judge Laurence Rittenband will decide Oct. 9 whether to certify, reduce or overturn the verdict.

''In my judgment, there is absolutely no legal basis for either the judge or the court of appeals to diminish or reverse the jury award,'' said Neufeld attorney Daniel C. Rosenberg.

Neither Orion nor Rosenzweig would comment, saying the matter was still in the courts.

Neufeld said he had contracts with Orion, then Filmways, and Rosenzweig entitling him to 50 percent of whatever the studio paid Rosenzweig during the first five years of ''Cagney & Lacey.'' The 1982-88 CBS police drama starring Sharon Gless and Tyne Daly was a Rosenzweig Prods.-Mace Neufeld production.

Rosenzweig made more than $5 million off the series in addition to the amount included his original contract, Neufeld said, arguing he was entitled to a corresponding increase.
