The House in the Square (also titled I'll Never Forget You in the United States and Man of Two Worlds) is a 1951 science fiction fantasy film starring Tyrone Power and Ann Blyth.

Power plays Peter Standish, an American atomic scientist who is transported to the 18th century, where he falls in love.

His co-worker Roger Forsyth, who is worried about Peter's lack of social activities, takes him to a house in Berkeley Square he inherited.

He rushes out to the graveyard in front of his house, where he not only discovers Helen's grave, but that she died of grief shortly after he was taken away to the asylum.

[4] French actress Micheline Presle was originally set to co-star, but she dropped out in March 1951 due to illness.

[3] Bosley Crowther of The New York Times wrote "Although there are obvious intimations of the lovely play, Berkeley Square, in the movie I'll Never Forget You, which came to the Roxy yesterday, there is little of its poetry or magic," and dismissed the film as "a thoroughly unmemorable event".

Power is given little opportunity to show any of his humor and the entire mood of the film is lethargic and a bit sombre".

[6] However, Allmovie called it "A fairly haunting, if a bit slow romance";[7] and Mystery File wrote "It may seem at best a rather tired fantasy to you, and that’s fine.
