No.1 Tip To Enhance Scenes (pt 2)
Today, we’re going to take a look at another type of screenwriting reversal—the “force from the outside.” In this case, the reversal is another character (usually) that suddenly enters the scene, turning it in another direction. This is a very popular type of reversal.

One of my favorite “force from the outside” reversals is in the film Annie Hall in the “movie theatre line” scene. Alvy and Annie are in the midst of an argument as they queue for tickets. Alvy becomes more and more irritated and ends up berating a guy behind him for pontificating on Marshall McLuhan’s work when he knows nothing about it.
The “force from the outside” reversal occurs when, in order to settle the disagreement, Alvy steps out of the line and produces the real Marshall McLuhan who promptly puts the man in his place. Alvy laments, “Boy, if life were only like this,” as a short denouement and the scene ends. So, in both these scenes we have an escalation of conflict and a reversal which leads directly to the climax, and we’re done!
In a scene near the start of Pulp Fiction, Jules and Vincent interrogate three boys over the whereabouts of the mysterious suitcase. The tension escalates as Jules eats their burger, quotes the bible and then shoots one of them lying on the couch.
Tarantino could have just ended the scene with Jules and Vincent finding the case and leaving, but instead he adds a “force from the outside,” reversal…
One of the boys hiding in another room, bursts in gun blazing, and every bullet misses. Jules and Vincent, surprised to still be alive, turn their gun on him, shooting him dead. Scene over.
Both these examples were pretty surprising the first time you saw them, right? Always look for ways to surprise your reader like this with a reversal. Introducing a “force from the outside” is a great way to do it.
Go back over your script, looking again at any scenes that don’t have a surprising twist of some kind right before the climax. Chances are they could do with one, so get rewriting!
Good luck!
