Australian director Luke Sparke boldly ventures into this territory with a wild, dinosaur-brimming indie film called Primitive War that premiered at this year's San Diego Comic-Con. In a world that needs more dinosaur movies, Sparke has come to deliver, hosting a talented cast of Ryan Kwanten (True Blood), Jeremy Piven (Entourage), Tricia Helfer (Battlestar Galactica) and Nick Weschler (Roswell).
