If there’s one genre of film I love, it’s science fiction.  If there are two genres I love, they are science fiction and musicals.  So you can imagine that during the very rare occurrences that there is an actual musical scene in a science fiction movie (or, I suppose, the more frequent occurrence of a science fiction musical), I’m simply giddy.  Not all science fiction has to be gritty or bleak – just read some Vonnegut to see why – and a good musical number in a science fiction movie is, for me, almost always entertaining.

It wasn’t easy – especially since I tried my best to avoid scenes from science fiction musicals – but I compiled 10 clips of singing scenes from science fiction movies.  Check them out below, and let me know if I left anything off.

The Diva from The Fifth Element

A very cool scene in The Fifth Element where the blue Diva hits notes that only an alien could.  Sucks about those stones, though.

Audrey II in Little Shop of Horrors

Yes, a man-eating, blood-drinking plant from outer space counts as science fiction.  You can take your pick of any of the songs in this great movie, but I’ve always been a huge fan of “Feed Me.”

The National Anthem in Southland Tales

One of these days, I’ll have to review this absolute trainwreck of a movie.  There are, however, some good scenes and some cool concepts, and I do like this rendition of the Star Spangled Banner.

Alex DeLarge doing “Singin’ in the Rain” in A Clockwork Orange

Click through to watch the clip.  NSFW, but you should probably know that.

Marty McFly in Back to the Future

Of course, the logic of Chuck Berry discovering Rock N’ Roll and “Johnny B. Goode” because his cousin Marvin called him while Marty was on stage playing Chuck’s future song doesn’t make a lot of sense, but I’ve always been more than willing to overlook that in light of Back to the Future‘s timelessness.

The Rocky Horror Picture Show

Like with Little Shop of Horrors, you can really take your pick of any of the songs – but here’s some young Meat Loaf for ya.

Princess Vespa in Spaceballs

It’s amazing how well this comedy holds up today, but you can say that about almost all of Mel Brooks’ movies.  This isn’t a big musical number or anything, but it’s a quick, funny scene that does involve some singing.

HAL 9000 singing “Daisy Bell” in 2001: A Space Odyssey

Absolutely creepy beyond belief.  Anyway, Kubrick chose “Daisy Bell” as HAL’s swan song (pun intended) because that’s the song the first “singing” computer performed back in 1962.

“Puttin’ on the Ritz” in Young Frankenstein

One of the funniest scenes, to me, in any movie ever.  R.I.P. Peter Boyle.

Mac singing Little Richard’s “Long Tall Sally” in Predator

Look, it wasn’t easy coming up with 10 examples of singing in science fiction movies, but dammit, Mac is doing his best to belt out some Little Richard, and for that he deserves credit.
