What is "moonwalker"

n. One who moonwalks; an astronaut who has walked on the moon.

Michael Jackson's Moonwalker, is a 1988 American anthology film starring Michael Jackson. Rather than featuring one continuous narrative, the film is a collection of short films about Jackson, several of which are long-form music videos from Jackson's Bad album. The film is named after the dance technique known as the moonwalk, which Jackson was known for performing in the 1980s. The name of the dance move was dubbed by the media, not by Jackson himself; however, he did choose the title of the film himself.
