Bigger Than Life is a 1956 American drama film directed by Nicholas Ray and starring James Mason, Barbara Rush, and Walter Matthau. Its plot follows an ailing school teacher and family man whose life spins out of control when he misuses cortisone. It is based on a 1955 article by medical writer Berton Roueché in The New Yorker, titled "Ten Feet Tall". In addition to starring in the film, Mason produced it.

Though it was a box-office flop upon its initial release, many modern critics hail it as a masterpiece and a brilliant indictment of contemporary attitudes towards mental illness. In 1963, Jean-Luc Godard named it one of the ten best American sound films ever made.
