What the hell are you supposed to do when suddenly one night, during your birthday celebration moreover, your old and physically exhausted grandfather shows up on your doorstep and begs of you to disregard everything and drive 300 miles to bring him back home? You could refuse and put him on a bus, seeing that he also managed to find his way there alone perfectly fine, but – like the cute woman accompanying him already pointed out – he is your grandfather and you just don't do a thing like that. So what other option is there but to politely offer a ride to both gramps and the lady? During the road trip, however, granddaddy reveals he's entangled in a spiritual battle with a ancient witch called Dsonqua and you are involved through your bloodline. A-ha! That immediately explains the eerie hallucinations you're having about wicked witch masks inside the pool and outside your bedroom window! All this is what's happening to Jan-Michael Vincent in "Shadow of the Hawk"; an above average compelling and atmospheric 70's thriller with a good cast and astonishing Canadian filming locations. Especially the first half of the film is more than fascinating to observe, what with all the mysterious Indian mythology and the genuinely creepy images of the witch's frightening mask. Unfortunately the film loses quite a lot of its pace and interest halfway and ends up being a rather dull and unmemorable supernatural hocus-pocus thriller. The most exciting moments of "Shadow of the Hawk" occur during the road trip, like for example the crash into an invisible wall, whereas the long-anticipated climax battle against the witch and her disciples is tedious and disappointing. George McGowan, known from the nature-revolts classic "Frogs", directs with a noticeable disinterest, but luckily the cast is excellent. Chief Dan George and Jan-Michael Vincent (one of my personal heroes of the 70's) are terrific and very believable as the Indian saviors. "Shadow of the Hawk" is quite difficult to track down these days, so make sure you only take the effort in case you're really interested in the film.
