Doddering Vicar
I think this role adds immeasurably to the flic;
it gives some comic relief which adds a dimension to the already moody and fine film by Hammer.
We discover he's quite the wag for spiders and is recognized as an expert in the field on a world scale.
This same actor was splendid in "Brides of Dracula" also with Cushing as a superb Van Helsing.
Incidentally we also have a splendid Watson who,too,further spices this definite Classic !
