The main theme was composed by John Williams for Superman: The Movie in 1978, the Richard Donner film starring Christopher Reeve as Clark Kent and Superman. Its opening fanfare became inseparable from the character across sequels, trailers, television references and countless parodies. Online, the recording by the Royal Philharmonic Orchestra is shared as a ready-made heroic cue, dropped under entrances, rescues and ironic glow-ups. Because the melody signals heroism instantly without any dialogue, it remains a go-to musical shorthand for courage, hope and over-the-top triumph in edits and memes today.
