Marty Feldman was taken from us too soon when he passed away in 1982 in Mexico, where he was working on the movie, "Yellowbeard".
More than a decade earlier, after appearing on The Dean Martin Show and David Frost's At Last The 1948 Show, among others, Feldman, who'd had another series or two in his native England, starred in his own sketch comedy series, The Marty Feldman Comedy Machine.
The series lasted just one season, debuting in the US as a spring replacement series in April 1972, six months after its launch in the UK. Feldman's writing staff included Irish comic Spike Milligan and a couple of American writers who'd soon launch lucrative film careers behind the camera, Barry Levinson and Larry Gelbart.
If the opening animation looks familiar, it should. It's the work of Terry Gilliam (Monty Python's Flying Circus). Given the rapid pace of the sketches, I'd say Feldman was drawing from the inspiration of the Pythons and other comics.
Following is a sample episode with guest Orson Welles.
Edit, 7/3/2020: This is a different video, still with Orson Welles, but also with Spike Milligan.
Feldman also drew upon his experience with Dean Martin by getting producer Greg Garrison on board for Comedy Machine. Wikipedia claimed the show aired in the US on ABC, but with the Martin-Garrison connection, I'd suspect it was actually on NBC.
