WEREWOLF OF LONDON (1935) test make-up
At left, the first, unused test of Jack Pierce's werewolf makeup for WEREWOLF OF LONDON; at right, the final version (teeth definitely appear to be the same). According to the excellent UNIVERSAL HORRORS: THE STUDIO'S CLASSIC FILMS, 1931-1946, by Tom Weaver (no relation, at least that I’m aware of) and Michael and John Brunas:
(The book then goes on to describe some rather delicious drama between Hull and Pierce involving pulling rank and werewolf life-casts. Do check out the book - fantastic stuff.)
Controversial opinion: while WEREWOLF OF LONDON is a lesser film than THE WOLF MAN and Glendon less endearing (to a fault) than Chaney's Larry Talbot, I far prefer Pierce's (well and truly resisted) Hull-werewolf makeup to his classic Chaney-werewolf 'do. There's something about it that I find far more haunting: perhaps it's how recognizable Glendon is inside the wolf. Makes the story that much more tragic?
