Friday’s openings redux: Spies and castaways

Two additions to the week’s mainstream (more or less) movie offerings:

“Swiss Army Man” : Paul Dano plays a guy marooned on a desert island, and Daniel Radcliffe plays the corpse that becomes his fantasy helper. My favorite headline explainer: “Cast Away” meets “Weekend at Bernie’s.” Bring an imagination. And maybe a strong stomach.

“Our Kind Of Traitor” : This spy flick tells the story of an ordinary man (Ewan McGregor) who becomes involved in a Russian man’s attempt to defect with his family. What you need to know: It’s based on the John Le Carré novel .
