Legend has it that there's a secret elixir called "Spanish Fly," which will have women unzipping your fly nearly immediately after they consume it. It's a myth, but a persistent one. From that urban legend emerged the German play which would become the British sex comedy, Spanish Fly (1976). The movie begins when a scheming British businessman named Sir Percy de Courcy (Terry Thomas) decides he'll buy some cheap Spanish wine, swap the labels, and pass it off as high end French stuff. But when some Spanish flies get into the vino, suddenly he's got a magical elixir that makes women insatiably horny. He just doesn't know it! He gives some to his old rival: photographer Mike Scott (Leslie Phillips), who shares some with the lingerie models he's snapping photos of, only for them to demand he has sex with them! After the screwing, Mike puts two and two together. Convinced Sir Percy has no idea the potential of his easy pussy elixir, Mike tries to buy him out to keep his models putting out. But all that does is make his old rival suspicious of why he's so interested in the cheap swill. This is no business rivalry movie, it's a sex comedy, so we'll get to see plenty of women without their clothes on. Andrea Allan shows her bouncy breasts taking a shower, and not caring at all when a man walks in on her. She even asks him to wash her back as she jiggles her rack! Whoa. Every guys has gotta get some of that fly! Meanwhile, the German model Nadiuska gets her shirt wet falling off a boat, and decides she's rather spend her time topless in the sun rather than wear wet clothes. We sure wish it was real, because nothing can open the thighs like Spanish Fly!
