One hundred percent. I work in film, and recently had an argument with a friend around this point. He's incredibly healthy, and frequently works a large number of unsociable hours. I was pointing out that filmmaking hours make no concession for family or age. He'd convinced himself that he'll have no more difficulty doing 80 hour weeks in his forties and fifties than he does in his mid thirties, because he 'takes care of himself'. The implication being that everyone could work those hours if they just ate better and held multiple martial arts belts as he does. It was no use pointing out that he'd confused cause and effect.
For set related jobs, the hours are the shoot. If the shoot runs long, everybody's on set. It's an exploitative - and in my view, completely unnecessary - culture. The marriages, parental relationships and health costs cannot be justified by the supposed necessity of dollar savings. But currently - especially in the US, film sets all to often work sweatshop hours. More enlightened practices, like 'French hours' (a ten hour day), are also possible. The films created under these conditions don't seem any worse, and the people involved are inarguably happier and healthier.
