Don Juan DeMarco is a 1995 American romantic comedy-drama film starring Johnny Depp as John Arnold DeMarco, a man who believes himself to be Don Juan, the greatest lover in the world. Clad in a cape and domino mask, DeMarco undergoes psychiatric treatment with Marlon Brando's character, Dr. Jack Mickler, to cure him of his apparent delusion. But the psychiatric sessions have an unexpected effect on the psychiatric staff, some of whom find themselves inspired by DeMarco's delusion; the most profoundly affected is Dr. Mickler himself, who rekindles the romance in his complacent marriage.

The movie is based on two different sources; the modern-day story is based on director/screenwriter Jeremy Leven's short story Don Juan DeMarco and the Centerfold (the movie's original title before the studio changed it shortly before release), while the flashbacks depicting DeMarco's back-story are based on the more familiar legend of Don Juan, especially as told by Lord Byron in his version of the legend.

Depp received the London Film Critics Circle Award for Actor of the Year, along with his performance in Ed Wood while the film's theme song, "Have You Ever Really Loved a Woman?", co-written and performed by Bryan Adams, was nominated for the Oscar, Grammy, and Golden Globe Award for Best Original Song.
