With its businesslike score and wood-panelled rooms swimming with testosterone, it’s no massive departure from the established formula for wartime drama. But this is solidly watchable stuff, elevated by top-tier acting talent.

I think Andrew Scott is terrific in the lead.

How do you make nerdy militarians talking, studying and map-reading in a time of crisis feel particularly cinematic? The answer is you keep it tight -- Pressure is, blessedly, a lean 100 minutes.

Thanks to its spotlighting of little-known history and the opportunity to see Andrew Scott play someone very good at their highly specific job, Pressure is well worth a look, particularly for war film aficionados.
