New Zealand actor KJ Apa broke his hand while filming Riverdale but kept it hidden from everyone, opting to soldier on and keep filming instead.
The 20-year-old, who plays Archie in the hit show, says he didn't even realise himself he'd injured himself as badly on the day.
"That was a gnarly day of shooting, I'll tell you that much," Apa said in an interview with TV Line.
"I wasn't really punching the ice, but I got a little bit too excited. I was punching a foam mat... [that was] sitting on the ice... It was cold, so I didn't really feel it. It wasn't until 20 minutes after that I realised I broke my hand. I didn't tell anyone."
Apa still seemed to enjoy the episode a lot - even suggesting the injury merely added to his excitement, calling it "mental" in a tweet from April.
Riverdale is on Netflix in New Zealand.
