"Knight Rider" is a classic TV series that was first aired in 1982, starring David Hasselhoff as Michael Knight, a high-tech crime fighter. In 2008, a made-for-TV movie titled "Knight Rider" was released, which served as a backdoor pilot for a potential new series. The movie was not widely released in theaters and was primarily intended for TV or home video.
