Beach lovers, beware! A creepy beast is loose on the shores of Malibu!

Sand predator Matthew McConaughey was caught sucking the life out of an unknown actress during a scene for his new film, "Surfer Dude." Breathtaking!

Matt's scene directions required him to smother the sheepish ocean creature, whose only line of defense was to wave her Godzilla feet!
