The actor profession often implies exit from the "Comfort Zone". If you need to do something not peculiar to your nature, or just something is not very pleasant - be kind, do it. Play a few doubles under the ice rain. Go for hours under tons of makeup. Or, for example, undressing - if the script requires.
In fact, no coercion is not: when the actresses of the core are about the fact that their young and inexperienced almost force is forced to shoot clothes in front of the camera - this is lies. The contract is clearly prescribed by the role and the actions necessary for filming. And participation in such scenes is always coordinated additionally. And if the actors go to failure, there are always a number of technical solutions how to achieve the desired picture. For example, body-colored overlays are made, or false parts of the body - also in the skin color. Later on the computer, the necessary parts of the body are drawn.
Verified Reception: Using Doubles. Just like cascaders, only for more personal moments. The time of such filming is at least the staff at least: actors, director with the operator.
And this item is often becoming controversial when signing the contract: not all actors and actresses are ready to go on a bold step. But if you are an ascending star, which makes the first steps in Hollywood, then choose especially not to come. So it was Kate Winslet, who received a major role in the Titanic. The scene was shot by the scene, where the main character draws Rose. Now this scene is one of the most famous in the history of the movie:
It turns out that Keith became incredibly shy before shooting. Leo was already quite recognizable at that time, which was additionally confused by a young actress. How to overcome awkwardness? Yes, just: when meeting Leonardo Kate opened clothes, under which it was ... nothing. She managed to cope with the excitement, but Dicaprio - no: when the scene shoots directly, and Kate dropped clothes, he was confused, and began to confuse words. "Sit on the bed ... on the sofa," Dicaprio told her. His embarrassment came to the soul of James Cameron: the director decided to leave the scene in such a natural form.
