Drexel Jerome Lewis Bixby was an American short story writer and scriptwriter. He wrote the 1953 story "It's a Good Life", which was included in The Science Fiction Hall of Fame. It formed the basis of a 1961 episode of The Twilight Zone and was remade in Twilight Zone: The Movie (1983). He wrote four episodes for the Star Trek series: "Mirror, Mirror", "Day of the Dove", "Requiem for Methuselah", and "By Any Other Name". With Otto Klement, he co-wrote the story upon which the science fiction movie Fantastic Voyage (1966), the related television series, and the related Isaac Asimov novel were based. Bixby's final produced or published work so far was the screenplay for the 2007 science fiction film The Man from Earth.

The Twilight Zone is an American media franchise based on the anthology television series created by Rod Serling in which characters find themselves dealing with often disturbing or unusual events, an experience described as entering "the Twilight Zone". The episodes are in various genres, including fantasy, science fiction, absurdism, dystopian fiction, suspense, horror, supernatural drama, black comedy, and psychological thriller, frequently concluding with a macabre or unexpected twist, and usually with a moral. A popular and critical success, it introduced many Americans to common science fiction and fantasy tropes. The first series, shot entirely in black-and-white, ran on CBS for five seasons from 1959 to 1964.
