Adam Scott and Taylor Schilling in The OvernightTHE OVERNIGHT

Even with a goatee, Adam Scott has such a sweet baby face, and can exude such endearing boyishness, that when you see him in an early playground scene in his latest film, you're half-surprised that a more towering adult isn't pushing him on a swing. Yet longtime fans know that Scott also possesses a canny understanding of how to employ his naturally guileless countenance for tension (as in the 2002 thriller High Crimes) or melancholy (HBO's sadly ignored Tell Me You Love Me) or acerbic wit (Party Down, Parks & Recreation, and numerous et ceteras). And that chameleon-ic talent makes him perhaps perfectly cast in the new comedy The Overnight, writer/director Patrick Brice's three-quarters-successful chronicling of an alternately invigorating and deeply uncomfortable grown-up sleepover.
