Trivia, insights & behind the scenes
Peter Sellers was so committed to the role that he reportedly insisted on wearing actual prison-issue underwear for authenticity. Method acting, 1960s style.
This was one of the last pure Ealing-style comedies before the studio system's collapse — a farewell to an era where criminals were charming and authority figures were the real buffoons.
