The film concerns on Tom Newcliff (Calvin Lockhart) , a wealthy businessman , great hunter and sportsman living with his wife (M.Clark) and his foreman (Anton Driffing) at a luxurious mansion . He has pursued and hunted all kind species with exception a werewolf . Thus , he invites a group of six men (Peter Cushing , Charles Gray , Michael Gambon..) and women related with weird killings about the eating of human flesh and nobody can leave the location . One of the occupants turns into werewolf at the full moon and stricken a rare pollen flower . Then , he undergoes a dental and hirsute transformation at night and going on a murderous rampage every time the moon is full . Tom investigates the guest who converts in night beast and trying to chase him , increasing his enormous collection at his isolated lodge .

The movie is a detective story in which you are the detective . The question is not ¨who is the murder¨? but ¨Who is the werewolf¨? . After all the clues have been shown we will get a chance to give your answer . The picture is a crossover of Blaxexploitation's protagonists , Agatha Christie whodunit (Ten little Indians) , horror mythic about werewolves and even gimmicks -William Castle type- on its intervening period when give to public some seconds for resolving the strange enigma . The transformation of man into werewolf is simple without special effects . Calvin Lockhart as obstinate and relentless hunter is top-notch ; besides , being surrounded by a highly capable secondary cast . Special mention for Peter Cushing ,as always he is excellent as specialist of knowledge on Lycanthropy . The screenwriter provided a very serviceable and well-knit screenplay with suspense and tension , giving full rein to director Paul Annett's natural talent .

THE BEAST MUST DIE begins with some of the worst music for this film as you can image (other than Polka music). This twangy techno-70s music is just terrible and seems all wrong for a werewolf film. And, once the film gets starts, the sound track continues to blare--with music way too loud and invasive for the film. Rarely do I ever complain so much about a soundtrack, but it just hits you like a brick when the film begins.

The film begins with an exciting chase scene--so exciting that you can perhaps ignore the dopey music. It is reminiscent to the film THE MOST DANGEROUS GAME, as a man is being tracked by hunters. However, the hunting ground is very high tech--with motion detectors and microphones everywhere. It turns out that this weird setup was created by a rich guy so that he can invite a group of people there in order to determine which of them is a werewolf!! How, exactly, you'll have to wait to see.

The rest of the film plays a bit like "Ten Little Indians" (also made into the movie AND THE THERE WERE NONE). In other words, it's a bit of a waiting game until ultimately the true werewolf reveals itself. However, despite an interesting story idea, it's undone by a few dumb touches. For example, just when the rich guy is about to kill the wolf, his wife inexplicably stops him from shooting it--even though this wolf is tearing apart their doggy. The other dumb thing is that although this guy is supposed to be such an amazing hunter, he keeps missing--even at point blank range. He's not the only one--two others do the same thing. These moments are just plain sloppy and do so much to undo the good of the film. Plus, with all the rich guy's money, why doesn't he just lock everyone into cages and see exactly who is the werewolf?! The only big plus is the very ending--it's pretty cool.

The bottom line is that I hate films where characters must act stupidly to make the film work. It's a sign of lousy writing--and this film manages to take a very good idea and ruin it. It is watchable, but just barely.

Calvin Lockhart is a rich businessman and professional hunter and like Leslie Banks in that long ago RKO classic The Most Dangerous Game has summoned a bunch of guests. One of them he suspects is a werewolf and it's a full moon rising.

Sure enough the werewolf starts doing its thing and Lockhart even with silver bullets just can't get the job done In the end Lockhart does the job, but at a tremendous cost.

Enough blood and gore for any horror film fan. What I don't understand is that Lockhart and scientist Peter Cushing develop a werewolf test. Why didn't they use it earlier?
