Sharktopus!

Sharktopus Trailer Released And It Is Awesome (VIDEO): "At long last, what we've all been waiting for: a thriller about a Navy-engineered half-shark-half-octopus killing machine! Yeah, we know it sounds suspiciously like that old Dr Octagon song from the 1990s, but it's not. Instead, it's an absurd, low-budget made-for-TV movie from B-movie king Roger Corman that's coming out on NBC's SyFy Channel sometime this year.

The Sharktopus is the 'Navy's next super-weapon'--until it gets out of control. And when it inevitably does, it turns into a killing machine with a perverse predilection for beautiful blonde women in bikinis. The ruthless Sharktopus drags them off beaches, bungee cords, and boats, and is NOT DETERRED BY MACHINE GUN FIRE!"
