Bigger Than Life is an American film made in 1956 directed by Nicholas Ray and starring James Mason, who also co-wrote and produced the film, about a school teacher and family man whose life spins out of control upon becoming addicted to cortisone. The film co-stars Barbara Rush as his wife and Walter Matthau as his closest friend, a fellow teacher. Though it was a box-office flop upon its initial release, many modern critics hail it as a masterpiece and a brilliant indictment of the conformist 1950s suburbia.

Bigger Than Life was based on a 1955 The New Yorker article by medical writer Berton Roueché entitled "Ten Feet Tall".
