Stranger Genius Lynn Shelton’s newest film features her highest concentration of big stars yet—Rosemarie DeWitt, Ellen Page, Scoot McNairy, Allison Janney, and Ron Livingston—but it’s not like she’s gone Hollywood. Shelton keeps the scope small as a masseuse (DeWitt) develops an aversion to skin at the same time that her straitlaced dentist brother (Josh Pais) becomes a faith healer to the new agey crowd. The performances are all strong, but ultimately Pais steals the show with some electrifying, tightly wound physical comedy that makes a minimalist character sketch feel like a bravura performance.
