Some of the best editing I've ever seen.
I invariably associate this with that episode of "Supernatural" Brett stars in ("Mr. Nightgale")-- primarily because he's obsessed with seagulls in that one.
This is a real oddity, a five-part Italian miniseries whittled down to feature film length for home media release. Bears more than a passing resemblance to "Amuck!!" (1971).
Complete with classic Giallo inane-plot-twist-that-destroys-the-movie ending.
