"The Trial of Rosie O'Neill" has a background player in a wheelchair. I have a vague memory that "Lou Grant" did also. Madlyn Rhue performed substantial roles in a wheelchair on television a few years ago when she was disabled by something like multiple sclerosis. Arthritis, I think, was the ailment that confined Lionel Barrymore to a wheel- chair in the Dr. Kildare movies of the thirties
