Would You Believe These “Get Smart” Factoids?!
A Different Agent 86?
When the show was pitched to ABC, Tom Poston was chosen to play Agent 86. ABC rejected the show, which led to the producer pitching it to NBC. The network agreed to the show, but they wanted Don Adams, who was under their contract, to play the lead role. Poston would go on to star in the sitcom Newhart, which provided him with three Emmy nominations.
No one could play Agent 86 better than Don Adams, anyway!
