The Spike Jonze-directed movie will be simultaneously released to both IMAX and conventional theaters Oct. 16, the companies said.
"Where the Wild Things Are" is based on Sendak's classic work, which was the winner of the 1964 Caldecott Medal for Most Distinguished Picture Book of the Year.
"We're excited to provide audiences and fans of such a beloved adventure the chance to experience it in IMAX," Dan Fellman, president of domestic distribution for Warner Bros. Pictures, said in a statement. "The imagery and sound in IMAX will help further immerse audiences directly into the land of Wild Things and we look forward to sharing it with them."
"'Where the Wild Things Are' is an ideal addition to IMAX's fall film slate," added IMAX CEO Richard L. Gelfond. "We see this film as playing to audiences of all ages, and as our network continues to expand, we're pleased to reach more moviegoers than ever before with a classic story told in an unparalleled format."
The movie stars Catherine Keener, Forest Whitaker, James Gandolfini, Mark Ruffalo, Max Records, Lauren Ambrose, Chris Cooper and Catherine O'Hara.
