Reportedly during the WarnerMedia's CCXP panel, John Cena said this about filming The Suicide Squad:
There was a day where we shot on a roof top, where we’re all eating. I had to eat an empanada, and I took it upon myself to try to eat the entire empanada in a seamless take thinking that it’ll look great. But it was also a complicated shot for James. 31 empanadas later we got it right.”
That could be close to 9,000 calories.
Last year, he told Kelly Clarkson he used to eat three boxes of Tic Tacs a day, which he estimated to be 10,000 calories:
There, he seems to be absurdly off on the number of calories, unless when he said he was eating boxes of Tic Tacs, he meant cases.
