'Flash Gordon' (1980)
In the pantheon of Saturday-matinee action movies, Mike Hodges' take on the comic-strip hero Flash Gordon ranks somewhere near 1984's Supergirl and 1997's Steel (starring Shaq!) at the very bottom of the list. But it says something about its soundtrack, composed by Queen, that the band's "Flash's Theme" is likely the only thing you remember about the movie. (Flash, aaaa-ah...he'll save every one of us!) On the plus side, the film is one of the first to turn a notable rock group into movie composers — a trend that is still often seen today in movies like Oblivion (M83) and TRON: Legacy (Daft Punk).
