The Blind Side is a 2009 American biographical sports drama film written and directed by John Lee Hancock. Based on the 2006 book of the same name by Michael Lewis, the film tells the story of Michael Oher, a football offensive lineman who overcame an impoverished upbringing to play in the National Football League (NFL) with the help of Leigh Anne and Sean Tuohy. It stars Sandra Bullock as Leigh Anne, Tim McGraw as Sean, and Quinton Aaron as Oher.

The film was a commercial success, grossing $309 million on a $29 million budget. Despite mixed reviews from critics, Bullock's performance was universally praised, leading to her winning the Academy Award for Best Actress, the Golden Globe Award for Best Actress in a Motion Picture – Drama, and the Screen Actors Guild Award for Outstanding Performance by a Female Actor in a Leading Role.

The film was the subject of controversy in 2023 when Oher alleged the Tuohys tricked him into signing a conservatorship agreement instead of legally adopting him, which prevented him from receiving royalties while the family indirectly made millions.
