How to broaden the appeal of Joyful Noise with one simple tweak

We reimagine the upcoming warblefest to maximise its commercial potential. A pre-reimagination, if you will.

This quick fix will guarantee a box office smash across all demographics. And the most beautiful part? Works with ANY movie, no matter how lame, guaranteed!

Dolly Parton scoring headshots with a .44 Magnum? I would straight up watch the shit out of that with my dad.

Cheques to the usual address please, Hollywood.
