There’s an old Hollywood adage that goes: “Without a script, you haven’t got a movie.” Although, there have been several directors and producers that have tried to put the truth of that saying to the test over the years (The Fast and Furious films?) it is generally agreed that the foundations of every great film lies with a first class script.

Over the years some of the world’s greatest writers have spent some time in Hollywood including such big names as George Bernard Shaw, F Scott Fitzgerald, Aldous Huxley, Dorothy Parker, Tom Stoppard and Harold Pinter. A good script writer, people like Billy Wilder, IAL Diamond, William Goldman or Robert Bolt can turn a pedestrian subject into a masterpiece with a shower of dazzling dialogue.
