A clerical error on the part of 20th Century-Fox cost McDowall a likely Academy Award nomination for best supporting actor for his role as Caesar Augustus Octavian in
Cleopatra (1963). The studio erroneously listed him as a leading player rather than a supporting one. When 20th Century-Fox asked the Academy to correct the error, it refused, saying the ballots already were at the printer. 20th Century-Fox then published an open letter in the trade papers, apologizing to McDowall: "We feel that it is important that the industry realize that your electric performance as Octavian in Cleopatra, which was unanimously singled out by the critics as one of the best supporting performances by an actor this year, is not eligible for an Academy Award nomination in that category... due to a regrettable error on the part of 20th Century-Fox.".
