movies

Two examples:

Saving Private Ryan - Spielberg made the whole main cast go through 2 weeks of "hell week" boot camp. He made them suffer together.

Then he flew Matt Damon in on a private jet, put him up in a nice place, and made the rest of the cast fully aware of it.

So there was actually real animosity towards Damon for not having suffered like they did and you could feel it in the movie.

Inglorious Bastards - Quinton told Eli Roth they were going to shoot the "bear Jew" scene a certain day. He put him in the cave and filmed other things. Only to say they weren't ready for him.

He did this I think 2 or 3 days in a row.

When Roth finally comes out you can just see in his eyes the craziness and I can't imagine how it must have felt to finally be set free from this literal cage (cave).

What other examples do you know?
