text: The most recurring antagonist in the franchise, Blofeld appears or is heard in three novels: Thunderball, On Her Majesty's Secret Service; and You Only Live Twice; as well as eight films from Eon Productions: From Russia with Love (1963), Thunderball (1965), You Only Live Twice (1967), On Her Majesty's Secret Service (1969), Diamonds Are Forever (1971), possibly For Your Eyes Only (1981; the pre-title sequence of which shows an unnamed character resembling Blofeld fall to his death), Spectre (2015) and No Time to Die (2021). The latter two films are set in a rebooted continuity, which started with Casino Royale (2006). Blofeld also appears in Never Say Never Again (1983), a remake of Thunderball that was not produced by Eon.
  Blofeld has been played on-screen by Donald Pleasence, Telly Savalas, Charles Gray, Max von Sydow and Christoph Waltz, among others. It was initially a convention of the films not to show Blofeld's face, only a close-up of his hands stroking his white, blue-eyed Persian cat. His face is revealed in You Only Live Twice when he introduces himself to Bond for the first time in person.
  Many of Blofeld's characteristics have become tropes in popular fiction, representing the stock character of the criminal mastermind, with the stroking of his white cat often retained as a parodic allusion to Blofeld's character. This can be seen parodied in the Austin Powers film series with the character of Dr. Evil and his cat Mr. Bigglesworth, or in the cartoons Inspector Gadget, with the character of Dr. Claw and his pet M.A.D. Cat, and Danger Mouse, with the character of Baron Silas Greenback.
