IMO it is condescending to say "You're watching a movie!". Is that what you are going to tell the families who have lost loved ones that were not even aware that it was a "movie". In a movie, the ones who get killed, continue to live. What if that were your son or daughter? Would it still be a F'ng Movie? Did these people sign up for their role in the "movie", like soldiers who take an oath to protect their homeland, knowing in the back of their mind that they may make the ultimate sacrifice?
Come clean and admit that we are in a war! It's not a "movie". It is a spiritual battle.
