The very first Hitchcock movie I ever saw.
During my early years on this planet, my dad used to pack our family into the panel-sided Buick station wagon & take us to the drive-in theatre where we were exposed to alot of those 70's campy "when animals attack" movies, like Food Of The Gods, Night Of The Leapus, Swarm, etc...
Goofy escapist fare of whose cheese I ended up developing a taste for.
Therefore, when I first caught film on the on the tube, my initial reaction was "Coo-hoooooollll.... Kinda like the movie 'Frogs!'! Except with birds!"
