The actor teamed up with Richard Dean Anderson in the series, which ran from 1985 to the early 1990s and even had his real-life battle with blindness incorporated into the script.
Elcar, who suffered from glaucoma, told producers he was losing his sight, so they adapted his character, Pete Thornton, to match his medical condition. By the time the show ended, Elcar was almost completely blind.
He also appeared in movies The Sting and The Learning Tree.
