My friend Steve Fore, who has steered me to so many good movies in the past, tipped me off to this one, writing on Facebook:
Looking for a period war movie with horror elements that's wall-to-wall kineticism for 83 minutes? An homage to "Nightmare at 20,000 Feet," Bugs Bunny, and "Aliens" that transcends all three? That winningly draws on the go-for-broke non-logic and wild narrative implausibility of classic Hong Kong action movies? That has the heroine stuck in the belly turret of a B-17 for half the movie and makes that strategy both claustrophobic and thrillingly dynamic? ... [T]ry watching "Shadow in the Cloud."Good call, Steve! Shadow in the Cloud is everything he said it was, with an emphasis on kinetic implausibility. This movie is loony from start to finish. Chloë Grace Moretz may seem implausible as the hero, but she makes her abilities seem real amidst all the logic-free plot. It's non-stop action that doesn't overstay its welcome ... Steve was right to mention it's only 83 minutes long. Director/co-writer Roseanne Liang was unknown to me. She's a Chinese New Zealander who delivers an unpretentious popcorn movie. I always have time for those.
