One of the first TV dramas with two female leads, this police procedural show stars Tyne Daly and Sharon Gless as two very different detectives from New York. Starting out as a successful television movie in 1981 starring Daly and Loretta Swit, it was then turned into a series the following year. Swit wasn’t allowed out of her contract for M*A*S*H and had to give up the role. She was initially replaced by Meg Foster, who was then replaced by Gless when CBS decided that Foster was too aggressive and looked too similar to Daly.
