Dr. Seuss' The Grinch is an American 3D computer-animated Christmas comedy film produced by Illumination Entertainment. Based on the 1957 Dr. Seuss book How the Grinch Stole Christmas!, it is the third screen adaptation of the story, following the television special from 1966 and the live-action feature-length film from 2000. It marks Illumination's second Dr. Seuss film adaptation, following The Lorax (2012). The film is directed by Yarrow Cheney and Scott Mosier, and written by Michael LeSieur and Tommy Swerdlow. It stars the voices of Benedict Cumberbatch, Rashida Jones, Kenan Thompson, Cameron Seely, and Angela Lansbury, and is narrated by Pharrell Williams. The plot follows the Grinch as he plans to ruin Whoville's Christmas celebration by stealing all the town's decorations and gifts.
It has grossed over $509 million worldwide, becoming the highest-grossing holiday film of all-time, as well as the highest grossing Dr. Seuss film adaptation. It received mixed reviews from critics, who praised the animation but said the film added little to nothing new to the source material. It is the final adaptation released during the life of Seuss's widow Audrey Geisel, who served as executive producer of the film and died on December 19, 2018.
