Conception and writing After departing his role as
Doctor Whos
story editor in October 1964,
David Whitaker moved into freelance work. He was immediately commissioned to write the two-part
Doctor Who serial
The Rescue to begin the show's second production block. On 1 November 1964, producer
Verity Lambert commissioned Whitaker to write a four-part historical serial to balance its science-fiction stories. The scripts were delivered by 15 January 1965, and titled
Dr Who and the Crusades; working titles for the serial include
Dr Who and the Saracen Hordes and
The Lion-heart. The Third Crusade is a historical setting that had fascinated Whitaker; he found that some of the historical figures—namely King Richard and his sister Joan, whose affectionate relationship he considered "almost incestuous in its intensity"—were effective material for a character drama. Depictions of the sexual relationship between the siblings were cut from the script, partly as Hartnell found it unsuitable for the family show; Glover was disappointed by their removal. The serial depicts two historical events: King Richard's attempt at peace by offering his sister in marriage to Saladin's brother Saphadin in October 1191, and the ambush of King Richard near Jaffa in November 1191. The timing of the events were rearranged for dramatic purposes. Story editor
Dennis Spooner was impressed by the maturity and near-
Shakespearean nature of Whitaker's scripts.
Douglas Camfield was assigned to direct
The Crusade, having worked as a production assistant on earlier serials
An Unearthly Child (1963) and
Marco Polo (1964) and proven himself a capable director of the third episode of
Planet of Giants (1964). Hill enjoyed working with Camfield again, and O'Brien (who was newer to the series) found him dynamic; Hartnell was pleased to work with a director he liked. Camfield praised Whitaker's writing and research, declaring the serial "the best
Doctor Who script I've ever worked on". Barry Newbery worked on the serial's set design. He used the 1962 volume
Behind the Veil of Arabia by Jørgen Bitsch for inspiration. The images of the original architecture from the Crusades were particularly useful for Newbery. The props adorning the sets were hired from Old Times Props House. Camfield engaged
Dudley Simpson, who had previously scored
Planet of Giants, to compose the incidental music of
The Crusade. Nine minutes of music was recorded on 1 March 1965, performed by five musicians on a range of instruments.
The Crusade was the last collaboration between Camfield and Simpson; a falling out between the two shortly after the serial's airing led to Camfield's refusal to hire Simpson. When he became aware that he had misjudged Simpson many years later, Camfield intended to hire him again, but died before doing so. The serial used sound effects extensively.
Casting and characters {{multiple image |total_width=350 Camfield was impressed with Glover's performance in
An Age of Kings in 1960, which led to his casting in the serial. Glover expressed excitement to work with Camfield, and to work with Russell again; he found Hill welcoming, but felt that Hartnell was not fond of him. When it appeared that Glover may not be available, Camfield interviewed
Nicholas Courtney for the role, having known him at school in Egypt, but felt that he was not suitable. Marsh was cast as Joanna; she had previously worked with Hartnell in
Will Any Gentleman...? (1953), during which she met her husband,
Third Doctor actor
Jon Pertwee.
Adrienne Hill was also considered for the role, and read for Camfield and Lambert; they decided that she was not tall enough. Marsh recalled that she and Glover decided to act "slightly too loving for a brother and sister", which Lambert noticed and noted. The European actors in foreign roles were "
blacked up" for the serial by the make-up department. Walter Randall was cast as El Akir, having been good friends with Camfield since working together on
Gerry Halliday in 1951; Randall previously appeared in the series as Tonila in
The Aztecs (1964). Several other actors had also appeared in previous serials, namely
Marco Polo.
Filming Early
35mm stock filming took place from 16–18 February 1965 on the sound stages at
BBC Television Film Studios. Russell was released from rehearsals for "Invasion" (the fifth episode of the preceding serial,
The Web Planet) to perform action sequences on 16 February to accommodate for his holiday during the filming of the third episode; the first action sequence, a fight with a Saracen warrior, was choreographed by fight arranger
Derek Ware. For a shot in which ants advance upon Ian in the fourth episode, assistant floor manager
Michael E. Briant arranged for the supply of 75
black ants from
London Zoo. Russell refused to perform a shot in which the ants move up Ian's arm to his hand; Camfield's production assistant Viktors Ritelis
doubled for Russell instead. Hill was released from rehearsals for "Invasion" on 18 February to film for the serial. Rehearsals for the first episode began on 1 March 1965. Weekly filming began in Studio 1 at
Riverside Studios on 5 March 1965. For the first episode, a trained
hawk was supplied by John Holmes of the Formakin Animal Centre in
Benson, Oxfordshire. O'Brien was absent from rehearsals for the second episode on 11 March to film for the subsequent serial,
The Space Museum (1965). Russell was absent from filming the third episode as he was on holiday. The establishing shot of a desert in the third episode was sourced from of silent 35mm stock footage supplied by the ABPC Film Exchange. During recording of the final episode on 26 March, Lemkow injured himself with a knife, which went to a finger bone on his right hand; he was taken to hospital for a
tetanus shot. Camfield arranged for a cow carcass to be present during recording in order to achieve particular shots through the rotting rib cage; the carcass attracted flies and emitted an odour beneath the studio lights. == Reception ==
