Executive Meddling/Puppet Shows

A positive example of executive meddling is with the creation of Thunderbirds. The production company exec, Lew Grade, liked the show so much that he demanded that the half-hour show have hour-long episodes. As a result, Gerry Anderson's company had to, at least initially, pad the time with additional plot twists and character development, which gave the series a sophistication that made the show a cult classic.
Further executive decisions resulted in the cancellation of Thunderbirds after The Film of the Series failed to perform. This did, however, allow Anderson to develop his next show, Captain Scarlet And The Mysterons, which gathered a significant cult following of its own, if not as big as that of Thunderbirds. Grade made a less positive decision concerning Anderson's final Supermarionation show The Secret Service. Each episode featured Father Unwin, voiced by Stanley Unwin, bamboozling people with Unwin's trademark "Unwinese" doubletalk. Unfortunately, when Grade first heard this, he cancelled the show with only 13 episodes in the can, on the grounds that viewers wouldn't understand Unwinese -- despite the fact that they weren't meant to.
