On the sets of classic Hollywood movies

When they make a good movie, the viewer completely dissolves in it: worries about the characters, goes with them the whole path that the screenwriters have planned for them, admires the scenery, favorite actors and modern special effects. But have you ever wondered: how was your favorite movie shot? How did the director and his team manage to make this particular frame so realistic? How do actors behave on the set? What kind of atmosphere reigns on it? Perhaps these and other questions will be answered by this post about how things are on the set when the cameras are off.
