'The Visitor' aka 'Stridulum' (1979) -  Giulio Paradisi.

Frequent visitations to this sinisterly strange, reality-wrecking, wilfully wonky, Sci-High, 'Unidentified Film Oddity' shall inexorably lead to the permanent emancipation of your trash movie-mangled cerebrum's last fatally frazzled remnants! For me, maverick director Giulio Paradisi's cosmically kooky, trope-thrashingly trippy, horror/Sci-fi/fantasy misshape remains one UNIQUELY unbalanced, dramatically demented, blissfully psychedelic B-Movie brain-blaster!

'The Visitor' aggressively makes Swiss cheese of celluloid convention, taking lurid liberties with your logic-denied think sponge, and is scurrilously steeped in profound narrative incongruity. Perceived as a purely 'hallucinatory experience', rather than blithely dismissed as another whacked-out time-waster, the transgressive, inadvertently mythic, and not infrequently inventive, 'The Visitor' remains a monumentally mad, theologically twisted Euro-cult fever dream! Be strongly aware that Paradisis's fabulously far-flung phantasmagoria IS drugs, so it is strongly recommended that 'The Visitor' NOT be taken with any additional psychoactive substances, since pronounced, wildly unpredictable, and debilitating cognitive side-effects are inevitable! If Captain Beefheart had made a fast and bulbous, Sativa-slaked sci-fi/horror hybrid, it might be no less heroically tweaked than 'The Visitor'.

'I left the Allman Brothers for religious reasons, man!'

'The movie's kinda' hinkey, but I'm pretty good in it!!'
