I couldn’t let the 100th anniversary of the birth of Earle Hagen — one of the most important and most successful composers in TV history — pass without a look back at his massive impact on the medium. For this Variety story, I revisited the interviews I did when the Andy Griffith Show and Dick Van Dyke Show composer was posthumously inducted into the Television Academy Hall of Fame in 2011. Van Dyke, Marlo Thomas from That Girl, and Stacy Keach from Mickey Spillane’s Mike Hammer, all talked about Hagen’s role in setting the time, place and mood of each show. Hagen’s own words; those of fellow Emmy-winning composers Mike Post and protege Bruce Babcock; and YouTube clips of his classic themes, including I Spy and The Mod Squad, are also included.
