Two other attempts to escape were made during his time there but he never got beyond the camp grounds. He was subsequently sent to Stalag Luft III, near Sagan, the scene of The Great Escape.
Whilst at Stalag Luft III he met Talbot Rothwell, who later went on to write many of the Carry On films in which Butterworth was to star.
Butterworth was one of the vaulters covering for the escapers during the escape portrayed by the book and film The Wooden Horse. Butterworth later auditioned for the film in 1949 but “didn’t look convincingly heroic or athletic enough” according to the makers of the film.
