In my view when we are acting / watching (movie or drama), we are cheating ourselves . Because when we are acting in a movie or in a drama we are not real, we are just making fraud expressions i.e. we know already that we are acting, still we are expressing something else which is not ours at that time, more clearly, our outer expressions and inner feelings do not coincide. A truthful man will always be in a state of balancing outer expressions with inner feelings involuntarily. But when we are acting, we are voluntarily interrupting this system. i.e. we are showing outside what is not inside (completely fraud).
Can a bird/ an animal act in a role other than its own ? They are always be real. They don't know to be fraud.
The same happens when we are watching a movie/drama- we know that what we are watching is not real, but still we are forcefully trying to adjust our mind according to the seen.
