The Beast Must Die

Note to future self: If an extremely rich "friend" who enjoys hunting invites you to his house in middle of nowhere and tells you that you'll be spending the weekend without the chance of leaving, regretfully decline the offer and write off "friend".  1974's The Beasts Must Die is a film in which Tom Newcliffe (Calvin Lockhart), the rich friend, invites 5 of his friends that have all been strangely surrounded by tragedy wherever they go, to his sprawling estate for the weekend.  Tom is an avid hunter and has been said to "shoot anything that moves" in order to add it to his collection.  You might think from this description that Tom is interested in adding the Homo Sapien to his trophy collection, but in fact he's searching for something much more elusive.  Tom reckon's that the due to the strange circumstances surrounding the tragedies that his friends have been involved in, that one of them is... A WEREWOLF!
