Creator Backlash: Charles Bennett, one of the writers, hated the idea of including a female character and took his name off the film.
Fake Shemp: For the scenes shot on location in South Africa, doubles and stand-ins were used, as none of the lead actors travelled there for the shoot.
Missing Episode: The film was thought lost for years until it randomly turned up in the Pinewood vault.
Romance on the Set: Rumour had it that the sexual tension between Stewart Granger and Deborah Kerr crossed over into real life too, with the two actors having an extra-marital affair.
Star-Making Role: This got Stewart Granger noticed in Hollywood.
Throw It In!: The majority of natives on-screen were locals who were "recruited on the spot".
Wag the Director: Stewart Granger had the first director Compton Bennett sacked as they couldn't get along and the shooting was going nowhere. The next director Andrew Marton, being a man's man, hit it off instantly with Mr. Granger.
Errol Flynn was originally cast as Alan Quatermain, but turned it down, as he did not desire to sleep in a tent on location in Africa. Instead he did Kim (1950), which was filmed in India, but the accommodations for the actors were at a local resort.
Audiences at the initial screenings laughed their heads off at the scene in which Elizabeth Curtis (a Victorian Proper Lady) cuts her long hair off and it then cuts to her with a perfectly coiffed 1950s hairdo. Producers considered removing the scenes because of it, but couldn't find another way to explain Elizabeth's change of hairstyle.
King Solomon's Mines (1985 film, plus the 1987 sequel Allan Quatermain and the Lost City of Gold)
Franchise Killer: The Cannon Group had originally planned a trilogy of films, the third film was to be an adaptation of She and Allan but this was ultimately abandoned after the extreme negative reception of Allan Quatermain and the Lost City of Gold, coupled with the financial difficulties of the company at the time.
No Budget: Richard Chamberlain recalled being told that the budget was about $10 million. He joked that it was more like $3.75.
Troubled Production: Both films were shot concurrently in 1985; filming took six months and was torturous. Sharon Stone proved so difficult to work with — as her marriage was falling apart at the time — that the rest of the crew played mean pranks on her. The budgets were very low (Cassandra Peterson, aka Elvira, Mistress of the Dark, had no stunt double for her character's demise in the second film) and the filmmakers were even worried that the shoot was cursed.
John Hurt turned down the role of Allan Quatermain.
In 2011, a new sequel was proposed by Menahem Golan called Allan Quatermain and the Jewel of the East. The script was written by Menahem Golan and Richard Albiston, to be directed by Golan himself. The plot concerned Quatermain attempting to rescue his daughter from Chinese treasure hunters in the Congo. According to the 2015 documentary Golan: A Farewell to Mr. Cinema, Richard Chamberlain had agreed to return as the title character, but Golan died before the film began shooting.
