The Beast Shall Die (1974). Calvin Lockhart is a wealthy businessman and professional hunter and, like Leslie Banks in the RKO classic The Most Dangerous Game long ago, has summoned a host of guests. One of them that he suspects is a werewolf and it is a full moon rising. Sure enough, the werewolf started to do his job and Lockhart couldn't even finish the job with the silver bullet. In the end, Lockhart did the job, but at a great cost.
