”[Cat on a Hot Tin Roof] was originally to be filmed in black and white, as was the standard practice with ‘artistic’ films in the 1950s…However, once Paul Newman and Elizabeth Taylor were cast in the leads, director Richard Brooks insisted on shooting in color, in deference to the public’s well known enthusiasm for Taylor’s violet and Newman’s strikingly blue eyes.” (via)
