Churchill Schwartz and Oliver Stone

Bloomberg News has an early look from Cannes at Oliver Stone's "Wall Street: Money Never Sleeps": "Gekko discovers that he and Jake have a common love -- Winnie -- and a common enemy: the powerful banker Bretton James (Josh Brolin), whose firm Churchill Schwartz has powerful backers in the U.S. administration. Jake goes to work for Churchill Schwartz after his own firm's demise." I wonder why they chose the Jewish-sounding name Schwartz rather than something stereotypically, say, Irish or Italian?
