Did you ever notice how behind the scenes documentaries of films being made in, let's say, the past 20 years, always have the actors talking about how much fun they had on set? "oh, we had so much fun. It was a blast." yet behind the scenes documentaries from films made much earlier than that usually talk about the process of making the film. The challenges they encountered. Sometimes the stress of trying to get the shot. Never any mention of having fun.. I wonder if it's because back then, actors took their job more seriously.
