"the credits should read: Story by J. D. Zeik, screenplay by David Mamet. We didn't shoot a line of Zeik's script." Instead, Mamet received credit under a pseudonym. After the controversy over credits for Wag the Dog, Mamet decided to attach his name only to movies on which he is the sole writer. A disagreement over the 2–1 arbitration decision denying George Clooney a writing credit for Leatherheads led Clooney to become a financial core member of the WGA, rather than an active one. Variety's Michael Fleming wrote that "Clooney took a languishing 17-year-old project and got a greenlight after personally giving the script a major overhaul that transformed it into a screwball comedy", with Clooney asserting that he wrote almost the entire script, but only Duncan Brantley and Rick Reilly, who came up with the original concept, were credited.
