Near the end of production of the third season, the writers of "Cheers" had to deal with the death of one of the main actors. During the third season, Nicholas Colasanto's heart condition (which had been diagnosed in the mid-1970s) had worsened. He had lost weight and was having trouble breathing during filming. Shortly before third season filming wrapped, Colasanto was hospitalized due to fluid in his lungs. Though he recovered, he was not cleared to return to work. While visiting the set in January 1985 to watch the filming of several episodes, co-star Shelley Long commented, "I think we were all in denial. We were all glad he was there, but he lost a lot of weight." Co-star Rhea Perlman added, " wanted to be there so badly. He didn't want to be sick. He couldn't breathe well. It was hard. He was laboring all the time." Colasanto ultimately died of a heart attack at his home on February 12, 1985.
