Lloyd began his career as a writer in 1958 before making his film debut two years later in 1960 in "School for Scoundrels", and appeared in numerous film and television comedies during the 1960s and 1970s. Notably, he was a regular performer on "Rowan & Martin's Laugh-In" during the 1969–70 television season. Back in England, after the season had been completed, he met actress Joanna Lumley. A decision had to be made as to whether he would return to the U.S. for the start of the new season or remain in the UK and marry Lumley. He never returned to the United States.
