Quentin Durward
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".
