One of the very few films to get the blend of comedy and horror right.
Also notable for one of the best on-screen transformations ever...and done in broad daylight, which was unusual for the time...they were usually shot in dark, smoky backlit rooms (see the transformation from The Howling from the same year...clearly a lifeless puppet with rubber bladders being pumped full of air)
I actually worked in the cinema that was featured in the end (Eros Picadilly), though the actual cinema was only seen in a long shot, the foyer and inside of the cinema was recreated on a set.
Was that the cinema showing see you next Tuesday? I always remember the place showing adult movies, walking by of course and thinking of werewolves.
