Deputy Dwight "Dewey" Riley is the main deuteragonist of the Scream series. He's best known for trying to protect his little sister, Tatum Riley, and her best friend, Sidney Prescott during the first murder spree. He flirted with Gale Weathers and was nearly killed by Ghostface. When another killing spree started at Windsor College , Dewey rushed there to once again protect Sidney and stop the killers. He reconnected with Gale and was almost killed once again. When it looked like Sidney was in danger again, Dewey left Woodsboro for Hollywood , where he involved himself in the Stab 3 set. He investigated this killing spree as well and assisted in saving Sidney from Ghostface . When it was all over, he proposed to Gale. They were married and after a few peaceful years, another spree started. Dewey was now Sheriff of Woodsboro, and had a deputy named Judy Hicks. He, Gale, and Judy then saved Sidney's life once again, and it was (probably) all over.

Behind the Scenes
Behind the Scenes Dewey (David Arquette) and Gale (Courtney Cox) in ScreamHe was described "a big guy, 20's, handsome in a scrubbed-clean boyish way" in the Scream script.
As revealed on the Directors in 2007, David Arquette claimed that he presumptuously turned down the role of Billy Loomis for the role of Dewey.
David Arquette's character was originally written to die at the end of Scream. However, feedback from test screenings suggested that the audience would rather see Dewey alive at the end of the film instead of dead. This caused an additional scene showing Dewey being taken into an ambulance on a gurney, clearly alive, to be filmed and added to the end of the film.
In 1999, David starred alongside fellow Scream co-star Drew Barrymore in "Never Been Kissed", which also starred future Scream 4 co-star, Marley Shelton.
Dewey was the only Scream survivor not to break one of the Rules in the climax of the first film.
Ross Hoss initially appeared to be the "new" Dewey in Scream 4 but by the end of the film Judy Hicks seems to fill that role.
