God, I'd nearly forgotten about all those stupid videos they made them film, like they didn't have enough on their plates.
And yeah, he did, I'm pretty sure he mentioned that sort of thing more than once. I was kinda hoping he was joking... since no one really reacted to it, but realistically, probably not. That sort of thing is normalized in the culture of athletic people, and any kind of performer - they're all bonkers. Countless stories of nutty directors traumatizing or half-killing their actors to get a more authentic performance.
It's understandable, they have to be 'crazy' like that to be so good, but it's unfortunate that it can go too far sometimes. For example, I really hate those 'inspiring' videos of runners dragging injured competitors over the finish line. It's super messed up that they're so obsessed with a 'finish every race' mentality instead of focusing on making sure a race-ending injury doesn't become a career-ending one.
On the most recent US DWTS, one week one of the contestants had a stomach bug and was running off-camera to vomit throughout the live show. Her pro does the post-show interview by himself because she was dehydrated enough to have to go to hospital straight after the show. He tells the press about how before their second dance she was crying and saying she didn't think she could do it, and he encouraged her that she was strong enough, would regret it if she didn't push through etc and she did it. The fact that he was happy to tell this story and didn't seem to have any awareness that a lot of people would not see a 38 year old man pressuring an 18 year old girl into performing when she was that sick as a heartwarming story speaks to how toxic a culture these people live in. (I should point out that she's an Olympic gymnast - undoubtedly an even worse environment than the dance world. I would certainly hope he would have known he couldn't expect that kind of thing from a non-athlete celeb!)
The world would be a boring place without talented, driven people, but sadly there's a nasty side to it.
