When Bob Newhart finished up a six season run of The Bob Newhart Show he realized he was done playing doctor and wanted to make a fresh start on a strange and wonderful new show.
And thus Newhart was born, where Bob got to play Dick Loudon for eight seasons opposite the beautiful and talented Larry, Darryl and Darryl...and Mary Frann was pretty great as Joanna Loudon too.
Newhart was a show about the kooky characters found in small town America, and Bob found inspiration for the show while dining and people watching in the hotel restaurant at the Seattle Hilton.
Speaking of small town kooks- Larry, Darryl and Darryl were so popular after their appearance on the second episode they were made part of the regular cast from season 2 on.
And although both Darryl and Darryl were classically trained actors with loads of experience they were cast in non-speaking parts, and their contracts forbid them from speaking to the press or appearing in public as the Darryls.
