This hummingbird soars. It has that based-on-a-true-story feel, with all the urgency and verisimilitude of a real-life tale. A sad and visceral indictment of our society under the guise of a thriller, Kim Nguyen’s rousing cinematic elegy will sneak up on you, like its titular moth.

Despite esoteric subject matter, writer-director Kim Nguyen (War Witch) has crafted a smartly entertaining and unexpectedly human film with his financial thriller The Hummingbird Project.

As the geological, financial and personal barriers the cousins face grow increasingly absurd, the movie works up a satisfying sweat.

The Hummingbird Project is most of a great movie. Amiable performances and a deft pace combine with high-contrast storytelling, and the results are generally engaging. Sometimes funny, sometimes smart, always watchable. But perhaps the film’s dedication to turning a clever tale into something profound was a miscalculation. Perhaps there were simply better ways to spend the time.

Some of the supporting actors register, especially Michael Mando as the unpretentious but quick-witted chief engineer. But the only surprise is Skarsgård. He has played wife-beaters, vampires, rapists, and mute would-be detectives, but who’d have thought he’d make a credible nerd?
