In 1971, Feldman gave evidence in favour of the defendants in the obscenity trial for "Oz" magazine. He would not swear on the Bible, choosing instead to affirm. Throughout his testimony, he mocked the judge after it was implied that Feldman had no religion because he was not Christian. By this point, preparation had begun on "The Marty Feldman Comedy Machine" (1971–72), a television series co-produced by Associated Television (ATV) in the UK and the American Broadcasting Company, and which was produced at ATV's Elstree Studios, near London. This vehicle lasted for just one series.
