The last film of Allan Aynesworth. In 1895 he had created the role of Algernon Moncrieff in the first stage production of Oscar Wilde's The Importance of Being Earnest. His scene is shared with Edith Evans, who became famous for playing Lady Bracknell on stage and in the 1952 film version of A Importância de ser Honesto (1952).
Only film directed by Emlyn Williams. He made no secret of his inability to handle the technical aspects of film-making, giving great credit to the famous (and Welsh-born) film editor Russell Lloyd, who is credited as "associate director".
Richard Burton was only 23 when he made this film. He speaks (and sings) in his mother tongue, Cymraeg (Welsh).
