Although uncredited, the actor who played Number 1 was Anthony Dawson, who had played Professor Dent in the previous Bond film, "Dr. No", and appeared in several of Terence Young's films. In the end credits, Blofeld is credited with a question mark. Blofeld's lines were redubbed by Viennese actor Eric Pohlmann in the final cut. Peter Burton was unavailable to return as Major Boothroyd, so Desmond Llewelyn, a Welsh actor who was a fan of the Bond comic strip published in the "Daily Express", accepted the part. However, screen credit for Llewelyn was omitted at the opening of the film and is reserved for the exit credits, where he is credited simply as "Boothroyd". Llewelyn's character is not referred to by this name in dialogue, but M does introduce him as being from Q Branch. Llewelyn remained as the character, better known as Q, in all but one of the series' films until his death in 1999.
