Dennis Harvey Film CriticNazi ghouls have figured in plenty of horror movies, whether preserved (1966’s “The Frozen Dead”), newly bioengineered (1978’s “The Boys from Brazil”) or zombiefied (too many to list). Edging close to that terrain, “Burial” revolves around a corpse — the corpse, as far as WWII’s end was concerned — that does not reanimate or otherwise come “back to life,” but poses a grave threat nonetheless.Not-quite-horror despite its macabre theme and mood, this sophomore directorial feature for Ben Parker is a handsomely produced period thriller that delivers in terms of action and atmospherics, even if his somewhat convoluted story doesn’t maximally pay off. IFC Midnight is releasing the Estonia-shot U.K. production to limited U.S. theaters and on-demand platforms Sept. 2.
