One of the great but now-forgotten comedians was Bobby Clark, with his painted on glasses and his fast-talking, Groucho-like patter. Many people seem to have discovered Clark--myself included--from Leonard Maltin's 1970s book on great comedy teams. He was part of a double act, Clark and McCullough, with his childhood friend Paul McCullough, who tragically committed suicide in 1936. Many of the team's once buried films have popped up on YouTube in recent years.
What people don't realize is that Clark, although he never made another film, continued on as a stage comic, and even did quite a bit of early, live television.
