The Adventures of Tintin: Secret of the Unicorn is an upcoming 2011 American performance capture 3D film based on The Adventures of Tintin, a series of comic books created by Belgian artist Georges "Hergé" Remi. It is directed by Steven Spielberg, produced by Peter Jackson, and written by Steven Moffat, Edgar Wright and Joe Cornish. The script is based on three of the stories: The Crab with the Golden Claws, The Secret of the Unicorn and Red Rackham's Treasure.

Spielberg first acquired rights to Tintin after Hergé's death in 1983, and re-optioned them in 2002. Filming was due to begin in October 2008 for a 2010 release, but release was delayed to 2011 after Universal opted out of producing the film with Paramount, who provided $30 million on pre-production. Sony chose to co-produce the films.Producer Peter Jackson, whose company Weta Digital is providing the computer animation, intends to direct a sequel. Spielberg and Jackson also hope to co-direct a third film.
