The film was made at Nettleford Studios. It was used to help build up Joan Greenwood who Rank were trying to make a star.

Some scenes had to be re-cut for release in the US, notably when Margaret Lockwood and Dennis Prices's characters went on honeymoon together - their twin beds were too close together.


According to trade papers, the film was a "notable box office attraction" at British cinemas in 1947.

AllMovie called it "A "woman's picture" if ever there was one"; but Bosley Crowther in The New York Times was less sympathetic, calling it "...not an especially dramatic or otherwise appetizing serving of entertainment"; whereas Variety wrote "...his romantic melodrama will have rough handling by the highbrows, but should prove a box office winner. Story is on hokey side, but a tearjerker."

It is not among Lockwood's most highly regarded films.
