According to a date shown printed on the masthead of the 'London Evening News,' the action of this film takes place in September of 1952.
Final film of Arthur Lucan, although he continued to make live stage appearances as "Old Mother Riley".
Retitled "My Son, the Vampire" for its 1963 American re-release (six years after Bela Lugosi's death) to cash in on the success of Allan Sherman's album, "My Son, the Folksinger."
This was the final "Old Mother Riley" film and the only one in which Arthur Lucan's longtime partner and wife, Kitty McShane, did not appear as Mrs Riley's daughter. Lucan and McShane had a very bitter separation in 1951.
This was the only film in the series in which the main character is not called "Old Mother Riley" in the title. Still, many sources have incorrectly referred to this film as "Old Mother Riley Meets the Vampire."
