Simon Moore is a British screenwriter, director, and playwright. He is best known as writer for the 1989 six-part BBC miniseries about the international illegal drug trade, Traffik, the basis for the 2000 American crime film Traffic and the 2004 three-part USA network miniseries by the same name.^[1][2]

Moore won a Primetime Emmy Award in the Outstanding Writing for a Miniseries category for his script for Gulliver's Travels.^[3]

Moore wrote and directed the 1991 film noir Under Suspicion. He wrote the 1995 cult Western The Quick and the Dead in late 1992, writing it as a homage to the Spaghetti Westerns of Sergio Leone, particularly the Dollars Trilogy starring Clint Eastwood. Moore decided the lead character should be a female, stating that "when you introduce women into that kind of world, something very interesting happens and you have an interesting dynamic straight away." The names of the lead villain (Herod) and the town (Redemption) were intentional allusions to the Bible. Moore considered directing his own script as an independent film and shooting The Quick and the Dead on a $3–4 million budget in either Spain or Italy. Sony Pictures Entertainment purchased Moore's script in May 1993.^[4]

Moore wrote the teleplay for the 1996 miniseries adaptation of Gulliver's Travels, which won five Emmys, including Outstanding Miniseries and Outstanding Writing for a Miniseries for Moore. He also wrote the fantasy miniseries The 10th Kingdom and Dinotopia.

As playwright, he adapted Stephen King's novel Misery for the stage, with the play premiering in London's West End theatre in 1992 and revived in London in 2005.^[5][6]

Moore lives in Los Angeles, California.
