Forever is a 1921 American silent romance film, also known as Peter Ibbetson, that was written by Ouida Bergère and directed by George Fitzmaurice.

Then the young man runs into his childhood sweetheart, Mimsi (Ferguson), and their romantic feelings are rekindled.

Their dream-affair continues over the years, even after Peter kills her husband, the Duke of Towers, and gets a life prison sentence.

Famous Players–Lasky had planned in 1919 to bring all three Barrymores, Lionel, Ethel and John to the screen in a lavish production of the Du Maurier novel Peter Ibbetson for that year.

Never produced, the Peter Ibbetson project met the screen in the film known as Forever with Wallace Reid and Elsie Ferguson.
