It's up to the courage of the filmmakers to make art in cinema, not just business. John was rejected by studios, he borrowed money and did movies with his own money. You're either courageous or not. You have to find a way.
I like to always remind my dancers about ways to avoid injury. One of the basic ways to avoid injury is to always make sure to stretch and warm up your body. This will loosen up your muscles, which will help to avoid common strain injuries such as shin splints and ankle strains.
