The Beast Must Die (1974)
Presented for your consideration, <B>The Beast Must Die</B>, the only movie in cinematic history to come with its very own "Werewolf Break." https://www.youtube.com/watch?v=klfE_nescX0
Essentially, this film is an attempt to merge a werewolf movie with an Agatha Christie whodunnit, The Most Dangerous Game, and Shaft. If that sounds like a train-wreck waiting to happen... you'd be right. The so-called "plot" involves a wealthy big game hunter who really likes running around in leather without a shirt, deciding he wants to kill a werewolf, so he does the obvious thing, and invites six people he suspects *might* be werewolves to his country estate, where he politely announces that he intends to track and kill one of them. Oddly enough, the guests don't seem the slightest bit shocked by this behavior and take the whole "I'm holding you hostage and planning on murdering one of you" thing in stride.
The werewolf, by the way, is played by an adorable looking German Shepard who occasionally wears a clown wig. Nope. Not making that up. Luckily, their clever use of day for night filming, lets you really drink in those subtle details you might otherwise miss with proper lighting, editing and special effects.
Excellent suggestion! This film scared the hell out of me as a little kid... then, I returned to it as an adult and howled with laughter at the German Shepard Werewolf. The Crew could do a wonderful riffing on this one!
