In Money Monster’s opening sequence, you can sense director Jodie Foster and her cast going for the slick, workplace-comedy pizzazz of Aaron Sorkin’s walk-and-talks in The West Wing and Steve Jobs and not quite getting there. George Clooney, as the braying host of a Mad Money-esque financial-advice program, alternately smooth-talks and ignores technicians and guests minutes before air time, and Julia Roberts, as the show’s director, trails him with exasperated good humor. Yet something feels off. You recognize the jokes as jokes, but because they’re delivered with such over-calculated disregard and nobody appears emotionally connected to their dialogue, they’re not very funny. However, right after the live broadcast begins, a young man with a gun and bomb-lined jacket interrupts the proceedings, and threatens to kill the host unless his demands are met. And then the oddest thing happens: Money Monster starts to become really funny.
