The 'Harlem Shake' trend may be pretty much over, but that didn't stop actor Gerard Butler from making a video with some British troops -- a video that'll make you smile unless you're dead on the inside where it can't be changed.

The 'Olympus Has Fallen' star was with the troops for a special screening of the movie at an Army base when someone (we hope it was him) decided to film this little tidbit of deliciousness.

The clip follows the same formula as all 'Harlem Shake' videos, with the opening shot being of one person dancing (Butler) while those around them go about their business before things quickly turn into a frenetic dance party.

Watch Butler boogie with a hat and backwards jacket like he's lost his marbles, proving yet again that this dude knows all about fan service. If only he was wearing a helmet and yelling about Sparta.
