His searing lead performance in Son of Saul (2015) established Géza Röhrig overnight as a prodigiously gifted dramatic actor, but who knew he could also be funny? In this screwball comedy about death and mourning, he’s by turns hapless, endearing, and more than a little nuts as an upstate New York Hasidic cantor plagued by nightmares about his recently deceased wife’s corpse decaying in her grave. Determined to learn how quickly her dust will return to dust, he badgers a pot-smoking, burned-out community college science teacher (Matthew Broderick, master of the double take) for some hard data as to when her ruach (soul) is likely to return to God. Some cockamamie, quasi-scientific, and definitely not kosher experiments ensue; meanwhile, enthralled by a pilfered tape of the 1937 Yiddish classic The Dybbuk, the cantor’s two impressionable young sons (Leo Heller, Sammy Voit) decide dad needs an exorcism. Writer-director Shawn Snyder makes a strikingly original and winsome feature debut.
