Perhaps the greatest compliment one can bestow on a thriller is to call it Hitchcockian, and “Arbitrage” – written and directed by Nicholas Jarecki – would fit nicely in the Alfred Hitchcock catalogue. The movie’s power comes not only from the fact that it keeps viewers in suspense but from its carefully drawn lead character, Robert Miller (Richard Gere). Robert is a powerful hedge fund manager with an aura of complete confidence, yet viewers sense his vulnerability when he’s alone.
