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.
A concise route through Gary Burghoff's screen work includes M*A*S*H (1970) as Radar O'Reilly; M*A*S*H (1972) as Radar O'Reilly; AfterMASH (1983) as Radar O'Reilly guest appearance. These selected credits show different periods of the career without presenting the gallery as a complete filmography.
M*A*S*H is the clearest entry point in this selection. The 1970 production provides a recognizable role around which the earlier and later credits can be compared.
Across the selected roles, Gary Burghoff moved between different ensembles and production formats. Watch how posture, timing, vocal delivery and the character's place in the group change from one title to the next.
The productions represented here depended on recurring casts, directors, writers and crews. The gallery keeps the focus on credited work while avoiding claims about private relationships or undocumented production history.
The works span changing screen styles and audience expectations. Their dates help place each performance in its production era; they do not imply that every title began or ended with Gary Burghoff's participation.
