For a long time Ive vaguely assumed that Elektra Natchios, a character introduced by Frank Miller during his run on the comic book Daredevil, was inspired by Melina Havelock, a character in the James Bond film For Your Eyes Only (played by Carole Bouquet).
I mean, theyre both Greek, theyre both assassins, they both use retro weapons, and theyre both avenging their parents murder. Eachs commitment to revenge puts her at odds with her nominally anti-revenge but kinda-hypocritical-on-the-subject male love interest and story protagonist. They look something alike (frankly more than comic-book Elektra and later movie-Elektra Jennifer Garner do). And Melina even compares herself explicitly to the original Greek mythological figure Elektra, an avenger-of-a-slain-father after whom Millers Elektra is evidently named.
Alas for my theory, Millers Elektra made her first appearance six months before the Bond film was released. So Melina couldnt have influenced Elektra; and given the timing, influence in the other direction isnt feasible either. So its just a coincidence type thing deal. Drat!
