Director Mark L. Lester, who also gave us the Schwarzenegger masterpiece that is Commando (a.k.a. the most "Arnoldy" Arnold movie ever made) has brought to life Poseidon Rex, about a tyrannosaurus that can go underwater. Judging by the trailer, it also features a shit-ton more monster money shots than your average Syfy or Asylum production, even if the monster looks almost as fake.
It stars Brian Krause of Return to the Blue Lagoon. But the real star is a T-REX THAT SWIMS. This is sure to be the best trailer you'll see today that features mutated reptiles doing uncharacteristic things.
