His first stage appearance was at age 13 but his early hopes of becoming a serious actor were dashed when he failed an audition for the Royal Academy of Dramatic Art. He began to entertain during World War II service in the British Army. It was at this time that he adapted his surname to Howerd "to be different". In 1944 he became a bombardier in Plymouth, was promoted to sergeant, and on 6 June 1944 was part of the D-Day effort but was stuck on a boat off Normandy. Despite suffering from stage fright, he continued to work after the war, beginning his professional career in the summer of 1946 in a touring show called "For the Fun of It".
