The trailer for Avengers: Age of Ultron has proven a viral hit even by Marvel standards - 43 million hits and counting on YouTube as of writing. 

While the trailer itself is relatively brooding and atmospheric - certainly compared to the more playful Guardians of the Galaxy teasers - it takes nothing more than a soundtrack change for the trailer to play out very differently indeed. That is exactly what Martin Revelation Films have done, choosing to add My Heart Will Go On to the incredibly popular teaser.

Without Ultron's dramatic voiceover and the accompanying sombre music, the trailer's copious slow-motion shots and heavy doses of dramatic posing become hilariously ridiculous.

The original won't be quite as effective next time you see it:
