Quentin Tarantino's seven-minute ovation at Cannes looked incredibly awkward

Anyone who thinks a seven-minute standing ovation would get, well, a bit weird after the first couple of minutes would be absolutely correct.

Footage from the rapturous reception for Quentin Tarantino's Once Upon A Time In Hollywood at the Cannes Film Festival this week is now circulating online, and it makes for some pretty painful viewing.

The stars are there, including Brad Pitt, Margot Robbie, Dakota Fanning and Leonardo DiCaprio, all applauding away, along with Tarantino himself.

But as the clapping continues, it all becomes increasingly awkward.

Matters certainly aren't helped by the festival's cameraman, who lingers on each star for a toe-curlingly torturous amount of time, and not to mention just inches from their faces.

Oh, you can keep looking away Brad, but he’s still there...

Soon enough, it feels less like a celebration, and more like a gruelling endurance event, before starting to border insincerity.

Cannes is famous for its bizarre, ludicrously lengthy standing ovations, and Tarantino's seven-minute marathon is actually pretty small fry, even by his own standards.

Inglorious Basterds in 2009 got 11 minutes worth of clapping.

But even that's nothing compared to some of the real big hitters, applause-wise, in recent history.

Mud, with Matthew McConaughey, which competed for the Palme d'Or, but didn't win, won the clapping contest by racking up an 18-minute ovation.

In 2004, Michael Moore's documentary Fahrenhiet 9/11, which did win the Palme d'Or, nailed 20 minutes.

But Guillermo Del Toro's Pan's Labyrinth in 2006 beat the lot, grabbing what must have been an excruciating – not to mention physically painful – 22 minutes on non-stop clapping.
