[1] Richard Gordon recalled that there were plans to shoot additional scenes with Lugosi and without Arthur Lucan for the American market, but the idea was never put into motion.

Gordon also stated that the film emphasised that Lugosi's character was not a real vampire so that it would get a U certificate allowing children, who were Old Mother Riley's biggest audience, to see it.

Simple fun and hearty shocks, plus compelling title and star values, make it a sound attraction for the masses and youngsters, Good popular 'quota'. ...

The picture is a trifle laboured at the start and the most is not made of the vampire asides, but, no matter, laughs and thrills, fashioned in an evergreen mould, pile up towards the finish.

Arthur Lucan puts over his famous dame act with characteristic aplomb and sings a catchy ditty as Old Mother Riley and Bela Lugosi, although restrained, makes an effective foil as Von Housen.

The final schemozzle in which bicycle, motor-cycle and old crock car are employed is excellently timed and aptly rounds off the zany, cunningly cast low-life extravaganza.
