The Internet Movie Database, or IMDb, maintains a filmography for John Grisham that contains all adaptations of his written work along with films for which he served as a writer or producer. In its totality, it represents his entire body of filmed work both professionally and in adaptation of his earlier printed novels and stories.
Grisham is well-known for influential adaptations like "The Firm" and "The Pelican Brief," which helped to establish his mass-market appeal and his talent for legal thrillers. His work also includes more broadly comedic turns like "Christmas with the Kranks," for which he served as a writer and helped in production.
IMDb's writer and producer databases are updated regularly so that it continues to reflect the most recent work of a given individual. Grisham's page changes to include new adaptations and new uses of his work and, in 2015, he was still an active writer whose books were highly sought by Hollywood production firms.
Grisham's close involvement with Hollywood has helped to make his career as a writer an internationally recognizable one. Many of his novels, particularly his legal novels with their focus on hidden crimes and dark secrets alongside pulse-pounding action, have been adapted or sought for adaptation by various producers and his body of work is very extensive.
