The Blind Side is a 2009 American semi-biographical sports drama film. It is written and directed by John Lee Hancock, and based on the 2006 book The Blind Side: Evolution of a Game by Michael Lewis.

The storyline features Michael Oher, a homeless African-American youngster from a broken home, is taken in by the Touhys, a well-to-do white family who help him fulfill his potential. At the same time, Oher's presence in the Touhys' lives leads them to some insightful self-discoveries of their own. Living in his new environment, the teen faces a completely different set of challenges to overcome. As a football player and student in Wingate Christian School (a fictional representation of Briarcrest Christian School in Memphis, Tennessee), Oher works hard and, with the help of his coaches and adopted family, becomes an All-American offensive left tackle.

Sandra Bullock stars alongside Quinton Aaron as Michael Oher, Tim McGraw as Sean Tuohy, and Kathy Bates as Miss Sue. The movie also features appearances by several current and former NCAA coaches, including SEC coaches Houston Nutt and Ed Orgeron (Oher's coaches in college, though Nutt represented Arkansas at the time and therefore does so in the film) and Nick Saban (who was at LSU at the time and represents it in the film), former coaches Lou Holtz, Tommy Tuberville, Phillip Fulmer, as well as recruiting analyst Tom Lemming.

The Blind Side was produced by Alcon Entertainment and released by Warner Bros. According to Reuters, the film's production budget was $29 million. Filming for the school scenes took place at Atlanta International School and The Westminster Schools in Atlanta, Georgia, and it features many of their students as extras. The film premiered on November 17 in New York City and New Orleans and opened in theaters on November 20 in the rest of the United States and in Canada.

Academy Award winner Julia Roberts was originally offered Bullock's role, but turned it down. Bullock, who is not outwardly religious, initially turned down the starring role three times due to discomfort with portraying a devout Christian. According to Bullock, she felt she couldn't objectively represent such a person's beliefs on screen. But after a visit with the real Leigh Anne Tuohy, Bullock was not only won over, but also took a pay cut and agreed to receive a percentage of the profits instead.

The Blind Side was a box-office success, grossing over $300 million. The film was well-received by critics, who most notably praised Sandra Bullock's performance. Bullock went on to win the Academy Award for Best Actress, as well as the Golden Globe Award for Best Actress and the Screen Actors Guild Award for Outstanding Performance by a Female Actor in a Leading Role. The film itself also received an Academy Award nomination for Best Picture.
