7. Robert Towne
In 1974, Robert Towne won an Academy Award for scripting Roman Polanski's Chinatown but Chinatown isn't the only classic film Towne had a hand in. Aside from Polanski's masterpiece, Towne gave uncredited contributions to all time classics like Bonnie and Clyde, The Parallax View, and, most notably, the Academy Award-winning screenplay for The Godfather. Like Aaron Sorkin, Towne's talents weren't enlisted for highbrow films exclusively. Towne also contributed to The Rock (along with Sorkin) and to the critically lambasted but extremely profitable Michael Bay blockbuster Armageddon.
