On the big screen: Grudge Match

A pair of aging boxing rivals are coaxed out of retirement to fight one final bout — 30 years after their last match.

Billy “The Kid” McDonnen and Henry “Razor” Sharp, are two local Pittsburgh fighters whose fierce rivalry put them in the national spotlight.

Each had scored a victory against the other during their heyday, but in 1983, on the eve of their decisive third match, Razor suddenly announced his retirement, refusing to explain why but effectively delivering a knock-out punch to both their careers.

Thirty years later, boxing promoter Dante Slate Jr, seeing big dollar signs, makes them an offer they can’t refuse: to re-enter the ring and settle the score once and for all.

But they may not have to wait that long: on their first encounter in decades, their long-festering feud erupts into an unintentionally hilarious melee that instantly goes viral.

The sudden social media frenzy transforms their local grudge match into a must-see HBO event.

Now, if they can just survive the training, they may actually live to fight again.

Catch Grudge Match at cinemas on Friday.
