More often than not, movies these days are not created, they’re cobbled together like a casserole recipe using parts from other sources. In this instance, take Oliver Stone’s Wall Street, add an episode of Law & Order… any episode, doesn’t matter from which of the series…drop in a pinch of Bernie Madoff, and blend in a whiff of Pretty Woman, and you have Arbitrage. This new thriller is set against the perilous world of hedge funds and high finance, and is nothing if not topical.
