All names with an asterisk (*) are credited on the "Cast" page (p62) of "Knights of the Round Table: A Story of King Arthur - Text based on the Metro-Goldwyn-Mayer film" (Ward, Lock • London and Melbourne) [1954] A number of notable performers - the first two here appearing in several scenes and with several lines to speak - were uncredited. These include: Ralph Truman as King Marr of the Picts, Henry Oscar as King Mark of Cornwall, Desmond Llewelyn as a herald, and Patricia Owens as Lady Vivien. Valentine Dyall spoke the opening narration. Laurence Harvey was included as a cast member in an early edit of this article - and also on IMDb - but his participation in this film remains unconfirmed. The film had some sequences shot near Tintagel Castle, Cornwall, with local people as extras. Scenes for the first battle were shot at Luttrellstown Castle Estate in Co. Dublin, Ireland. Woodland scenes and the hawking scenes were shot at Ashridge Forest, Herts. The Torquilstone Castle set designed by Alfred Junge for "Ivanhoe" (1952) was expanded and re-dressed as Camelot. Most of the indoor filming was at MGM-British Studios, Borehamwood, Herts. George Sanders was originally cast as Modred but fell ill prior to shooting and was replaced by Stanley Baker, who had just made an impression in "The Cruel Sea" (1953). The film was apparently shot on Eastmancolor stock, like "Quentin Durward" (1955), but it was advertised only as being 'in COLOR magnificence'. [See poster on Infobox above.] The film itself credits no color process. IMDb attributes the prints to Technicolor's laboratory, but it is not listed as one of the corporation's film prints in Fred E Basten's book "Glorious Technicolor". According to MGM records, the film earned $4,518,000 in the US and Canada and $3,578,000 elsewhere, resulting in a profit of $1,641,000.
