[5] Film rights were purchased by Gainsborough Pictures who had enjoyed success during the war with a series of melodramatic movies, starting with The Man in Grey (1943), also based on a novel by Smith.

Stewart Granger and Jean Kent had previously appeared together in Fanny By Gaslight and Madonna of the Seven Moons, and Anne Crawford who had been in They Were Sisters.

[7] The film was meant to follow The Magic Bow, but that was postponed due to the illness of Phyllis Calvert so, Caravan had to be rushed into production.

[15][16] Another source says it was the most successful film at the British box office in 1946 after The Wicked Lady, The Bells of St Marys, Piccadilly Incident, The Captive Heart and The Road to Utopia.

[17] According to Kinematograph Weekly the 'biggest winner' at the box office in 1946 Britain was The Wicked Lady, with "runners up" being The Bells of St Marys, Piccadilly Incident, The Road to Utopia, Tomorrow is Forever, Brief Encounter, Wonder Man, Anchors Away, Kitty, The Captive Heart, The Corn is Green, Spanish Main, Leave Her to Heaven, Gilda, Caravan, Mildred Pierce, Blue Dahlia, Years Between, O.S.S., Spellbound, Courage of Lassie, My Reputation, London Town, Caesar and Cleopatra, Meet the Navy, Men of Two Worlds, Theirs is the Glory, The Overlanders, and Bedelia.

The New York Times wrote, "Granger and the rest of the cast alternate between grappling with stilted lines and an embarrassingly archaic situation with neither the players nor plot making much entertainment, while 'Caravan' moves with the speed of an oxcart.

"[19] TV Guide noted "strong direction, brilliant individual performances, and production values far above the usual run of British films work beautifully together as one melodramatic situation is piled on another.

The artificiality of many of the sets, and the fairly obvious back projection, don't add to the conviction – but realism is hardly a strongpoint in a film like this, though it does benefit from far more location shooting than most of its ilk.
