The Return of Captain Invincible

The late, great Terry Pratchett once called a movie "A series of bad moments pasted together with great songs and a budget of fourpence"...this is that movie. It's an Australian Superhero Musical Comedy film with songs by Rocky Horror Picture Show lyricist Richard O'Brien and composer Richard Hartley performed by Alan Arkin and Christopher Lee....if that doesn't sell you, I don't know what will.
