The gunbarrel sequence has opened almost every James Bond film since Dr. No in 1962, pairing the view down a gun barrel with a gunshot and the James Bond Theme. Created as the franchise's signature introduction, it became one of cinema's most recognised openings and a shorthand for espionage, style and danger. Clips of the sequence spread online through edits, parodies and reaction videos, where the instantly recognisable sound signals a spy moment without any explanation. Its longevity comes from that familiarity, as new Bond films and generations of viewers keep the cue alive.
