Young at Heart is a 1954 American musical film starring Doris Day and Frank Sinatra, and directed by Gordon Douglas.

Its supporting cast includes Gig Young, Ethel Barrymore, Alan Hale Jr., and Dorothy Malone.

The family welcomes Barney into their lives, but a feeling of genuine self-worth escapes him, though he is falling in love with Laurie.

He survives, and, with a newfound affirmation of life, finally writes the song he had been working on, finding his self-esteem in the arms of Laurie and their new baby.

Songs from the soundtrack were released as an album by Frank Sinatra and Doris Day, also titled Young at Heart.
