A review for Critic’s Notebook of Pioneer, Erik Skjoldbjærg’s conspiracy story set at the start of Norway’s economic miracle in which deep-sea diver Aksel Hennie gets on the wrong side of history. The thriller aspects require the odd car crash and hallucination, although none of that stuff is as interesting as the bits involving actors climbing in and out of decompression chambers in ratty knitwear, looking suitably harassed. Stephanie Sigman turns up, an intriguing piece of casting that the film makes no effort to turn into anything at all; but she wisely opts not to climb in and out of anything.
