Arguably, there is no long-running storytelling saga that endures quite like Star Trek. Fans of the universe created by Gene Roddenberry have kept Paramount's most profitable franchise alive even when the studio itself loses faith in it. Along with the Great Bird of the Galaxy, the writers, actors, and production designers from every incarnation are lauded for their contributions on and offscreen. However, among the Star Trek storytellers, the individual episode directors never get enough credit in the countless books, documentaries, or ever-present fan conventions around the world.
