Primitive War (now streaming on Hulu) stops just shy of putting tyrannosaurs in F14s, which is kind of a shame, really. But Australian director Luke Sparke puts them and a raft of other dinosaurs in the Vietnamese jungle during the Vietnam War, which is almost as ludicrous. How they got there is best explained by Battlestar Galactica vet Tricia Helfer donning a terrible Rooshyen ahcksent, or perhaps not.
