The Central Intelligence trailer promises a little Hart and a big Johnson - and even gives fans The Rock dancing in a fat suit.

Dwayne Johnson and Kevin Hart come together in this cop comedy from DodgeBall writer and director Rawson Marshall Thurber.

The usually buff former wrestler appears fat and flabby while dancing in the shower in the the first trailer that fans will just be dying to see once they watch this!

We're used to seeing the former looking ripped, toned and ready for a scrap - but the first teaser for the upcoming movie gives us a peak into an alternate reality where this certainly wasn't always the case.

The story follows a one-time bullied geek who grew up to be a lethal CIA agent (Johnson), coming home for his high school reunion. Claiming to be on a top-secret case, he enlists the help of the former "big man on campus" (Hart), now an accountant who misses his glory days.

The end of the trailer gives us the epic scene where the WWE star is completely unrecognizable as a fat teenager singing and dancing in the shower.

Fans get to see a younger Johnson a lot thanks to his openness on social media, but the sight of a chubby Rock in the shower grinding, singing and dancing really is something else.

Elsewhere in the trailer, watch Dwayne and Kevin fly through windows, get into hijinks in helicopters, take part in car chases and spar in shootouts. But nothing quite amounts to Dwayne’s transformation!

They aren’t the toast of critical circles, but Dwayne Johnson and Kevin Hart are doing just fine: The former, in 2013, was the highest-grossing actor in the world, while the latter’s current comedy tour is projected to be the most lucrative in history. Now the two have teamed up for Central Intelligence, the latest entry in Hollywood’s most shopworn genre: the buddy cop comedy.

Central Intelligence opens June 17th, 2016.
