SPECTRE Irma Bunt, Blofeld's assistant, in his short story "Blast From the Past", which is a sequel to "You Only Live Twice". In the Eon Productions James Bond series, which began in 1962 with "Dr. No", SPECTRE plays a more prominent role. The organisation is first mentioned in "Dr. No" as the organisation for which Dr. No works. This was changed from Fleming's novels, which had Dr. No working for the USSR. In the films, SPECTRE usually replaced SMERSH as the main villains, although there is a brief reference to SMERSH in the second Eon Bond film, "From Russia with Love"
Motifs in the James Bond film series title sequence for "Spectre". A contemporary artist usually sings during the title sequence and an instrumental version of the main track may also be featured as a leitmotif during the film, which repeats in various moods. Writing for "Rolling Stone", Andy Greene says that "James Bond title songs, as a rule, have the name of the movie in the chorus," though he notes that this is not always the case. "On Her Majesty's Secret Service" has an entirely instrumental credit sequence, though the film features an alternate theme, "We Have All the Time in the World", sung by Louis Armstrong.
