Trivia: Originally, the opening credits were going to be set to Radiohead's "Man of War", which was an unreleased song they recorded back in 1997. The producers refused that, citing that it would technically be ineligible for a Best Original Song Oscar. The producers also turned down another song Radiohead had specifically recorded for the film, calling it "too melancholy."
Trivia: With a budget of $250-275 million, Spectre is one of the most expensive films ever made, and also the most expensive Bond film.
Trivia: Quantum was initially intended to replace the organisation Spectre, as they didn't have the rights to use the name Spectre or Blofeld - these were owned by Kevin McClory (writer of Thunderball) at the time of Quantum of Solace. When Eon Productions regained the rights they reinstated Spectre, as in the books.
