The Adventures of Tintin (occasionally subtitled The Secret of the Unicorn) is a 2011 animated adventure film based on Hergé's Tintin comic book series. It was directed by Steven Spielberg, who produced the film with Peter Jackson and Kathleen Kennedy. Steven Moffat, Edgar Wright, and Joe Cornish wrote the screenplay for the film. It stars Jamie Bell as Tintin, Andy Serkis, and Daniel Craig. In the film, Tintin, Snowy, and Captain Haddock search for the treasure of the Unicorn, a ship once captained by Haddock's ancestor Sir Francis Haddock, but they face dangerous pursuit by Ivan Ivanovitch Sakharine, who is the descendant of Sir Francis's nemesis Red Rackham.

Spielberg and Hergé admired each other's work; the director acquired the film rights to The Adventures of Tintin after the author's death in 1983, and re-optioned them in 2002. Filming was due to begin in October 2008 for a 2010 release, but the release was delayed to 2011 after Universal Pictures backed out of producing the film with Paramount Pictures, which had provided $30 million in pre-production; Columbia Pictures replaced Universal as co-financer. The delay resulted in Thomas Brodie-Sangster, who was originally cast as Tintin, departing and being replaced by Bell. The film draws inspiration from the Tintin volumes The Crab with the Golden Claws, The Secret of the Unicorn and Red Rackham's Treasure. Principal photography began in January 2009 and finished that July, with a combination of voice acting, motion capture and traditional computer animation being used.

The Adventures of Tintin premiered in Brussels, Hergé's home region, on 22 October 2011. It was theatrically released in Europe by Sony on 26 October and in the United States by Paramount on 21 December. The film received positive reviews from critics, who praised the motion-capture animation, faithful character designs, visual effects, action sequences, cast performances and musical score. The Adventures of Tintin was also a commercial success, grossing over $374 million, and received numerous awards and nominations, including being the first motion-captured animated film to win the Golden Globe Award for Best Animated Feature Film, while John Williams was nominated for an Academy Award for Best Original Score. A sequel directed by Jackson has been announced, but has since stalled in development hell.
