One of William Castle's last films...(mebbe it was,either this one or SHANKS) was BUG (1975)...which was about firey oversized cockroaches.
Not so obscure with us B movie fans is The DEVIL BAT(1943) with Bela Lugosi.
...which was kinda redone with George Zucco in the Bela role and the FLYING SERPENT(1946) in the Devil Bat role!
Akim Tamiroff is a vulture-man in the VULTURE (1967).
A kin of the Flying Serpent and the Giant Claw is Larry Cohen's Q-the WINGED SERPENT (1982).
I know the volume is'nt very loud...but this rare trailer for The FLYING SERPENT is worth posting! The crappy monster looks kinda like a mini Giant Claw!
