So I just watched the teaser trailer to Frozen 2 and while I was getting superhero training vibes from Elsa's interaction with the sea, I realized that this is a musical which got me thinking, has there be a superhero musical movie?

Just to cover the obvious superheroes have been covered as a musical in different formats:

• Live Theatre: Spider-Man: Turn Off the Dark (2010)




• Television: "Duet" (The Flash) (2017)




• Web: Dr. Horrible's Sing-Along Blog (2008)

Something tells me there is a Bollywood movie or two that covers the topic, but primarily interested in Western intellectual property.

Thanks to @Valorum and @dmoonfire for Dr. Horrible, I'm going to amend my question to limit it to theatrical release, but if there is a straight to video earlier than Dr. Horrible, that would be interesting to know.

Yes. But it's so-so bad.

The Return of Captain Invincible is a 1983 Australian musical comedy superhero film starring Alan Arkin and Christopher Lee. It grossed a mere $55,110 at the Australian box office despite a budget of $7 million.[2]

There's a Youtube review

Not a movie, but a play and then a TV special. From Wikipedia:

It's a Bird... It's a Plane... It's Superman is a musical composed by Charles Strouse, with lyrics by Lee Adams and book by David Newman and Robert Benton. It is based on the comic book character Superman created by Jerry Siegel and Joe Shuster and published by DC Comics.

1966 for the play and about a decade later for the TV adaption.

(It's always been one of those things I am intensely curious but also terrified of ever seeing)

You could say Dr. Horrible's Singalong Blog might be considered a superhero and musical. Though it is a parody (with some good songs), it may not be what you have in mind.

There is in fact a Bollywood movie musical about a superhero!

Mr. India

A poor but big-hearted man takes orphans into his home. After discovering his scientist father's invisibility device, he rises to the occasion and fights to save his children and all of India from the clutches of a megalomaniac.

I would actually recommend watching it. It's funny/corny like Dr. Horrible but not too corny (I hate corny). There is actually a scene I wanted to turn into a meme, but I forgot what it was. Oh it's actually on YouTube.

Depending on where you draw the lines for "superhero movie" and "musical", various of the Lego Movies might count. For instance, here's a musical number from Lego Batman.
