About Gary Burghoff
Gary Rich Burghoff is an American actor who is known for originating the role of Charlie Brown in the 1967 Off-Broadway musical You're a Good Man, Charlie Brown, and the character Corporal Walter Eugene "Radar" O'Reilly in the film M*A*S*H, as well as the TV series. He was a regular on television game show Match Game from 1974 to 1979 for 204 episodes, standing in for Charles Nelson Reilly, who was in New York doing a Broadway play, and continued to make recurring appearances afterwards. Burghoff was nominated for six Emmy Awards for M*A*S*H in the category of Outstanding Supporting Actor in a Comedy Series and, of those nominations, he won an Emmy in 1977. Although he played the same character in the series as in the film, Burghoff has cited differences in the portrayal: In the original feature film M*A*S*H, I created Radar as a lone, darker and somewhat sardonic character; kind of a shadowy figure.
