Quincy television star Jack Klugman is suing TV executives at NBC, claiming they owe him royalties from his hit medical drama.The Hollywood actor insists he’s still owed profits from the hit show 25 years after it last aired and is insisting the studio is lying about the show’s worldwide profits. Klugman claims he is entitled to 25 per cent of all "net profits" from the show, and that NBC bosses haven’t been paying him.In the legal documents, Klugman claims he tried to get NBC to turn over all its papers regarding the show, but was turned away with a letter that said they were "unable to comply with your request." The 85-year-old also states his own copy of the contract was lost when his agent died, prompting him to demand the copy from NBC.The lawsuit aims to force NBC bosses to produce the contract and provide the cash he claims he’s owed, plus legal fees. Klugman says, "I recently heard that they made $250 million and it’s still on TV in Germany. I don’t want their money. I want my money. "I worked my tail off. I got up at four in the morning and stayed at the studio. I did rewrite, I edited."
