After glimpsing an assassination, estranged Manhattan spouses Hugh Grant and Sarah Jessica Parker are assigned to a witness protection program, flown to Wyoming, and installed in a one-horse town where there are no bistros, art galleries, department stores, or funny jokes. This soporific comedy is the work of writer-director Marc Lawrence, the King of Pap (Music and Lyrics, Two Weeks Notice); with Sam Elliott, Mary Steenburgen, Michael Kelly, and Elisabeth Moss. PG-13, 103 min.
