The Big Finish: Tips for Act Three

By:

In some respects, writing your third act is the easiest part of your script. You’ve done all the exposition, the audience has fallen in love with your characters, and the only thing left is explaining how the story resolves. Well, maybe it’s not that easy. You do have to answer all, or at least most, of the questions you’ve raised, let the audience know what happens to each of the characters, tie up every loose end and make it all really, really exciting.

Here are some hints to get you started.

Answer all the Questions

Most of the questions you’ve raised in the script should be answered. Even when you’ve chosen to use an ambiguous ending or are writing a sequel, you need to answer most of the questions you’ve raised. You’re ending needs to feel satisfying and the only way to do that is to answer the questions. You can sometimes raise another question if you’d like, though. The end of The Graduate raises the question “What now?” The main question of the film, “Will he get the girl of his dreams despite having slept with her mother?” has been answered and now it’s time for a new question. (For an interesting article about this scene go here.)

The answers should also include how and this is where you get most of your third act. At the end of the second act your hero faces a ‘dark moment’ he’s not going to get what he wants (or he’s triumphant if you’re writing a tragedy). The narrative question then becomes, “How will he recover from this and get what he wants?” (or, self-destruct, if it’s a tragedy.) That how is where you get most of the action for Act Three.

Supporting Cast

Aside from answering all the questions, by the end of the third act we should have a clear idea what happens to the supporting characters. You don’t want to leave the audience wondering, “What happened to so-and-so?” All the lesser characters need to get their just deserts, good or bad. In The Devil Wears Prada Andy rejects the sexy journalist, returns from Paris and gives all of the clothing she’s been gifted to Emily, and even has a healing moment with her ex-boyfriend. All the lesser characters are wrapped up.

The End That’s Not the End

Horror movies are big on this technique, though you do sometimes find it in other kinds of movies. Alien is a great example, Ripley could get away but she goes back for the cat, Jones. This is a somewhat controversial and perhaps transparent extension of the tension. You can use a ‘false’ ending in any kind of story, though. The detective puts the killer away, only to realize he’s not the killer. The hero very nearly marries the wrong girl only to change direction and marry the right girl.

The Big Twist

Sometimes a ‘false’ ending is closely related to The Big Twist. If you’re writing a thriller you want to save a big twist for the third act. A great example of a third act twist comes in Body Heat. After manipulating, inept lawyer Ned throughout the movie Matty appears to die in an explosion leaving Ned to face prison time for killing her husband. While in prison, Ned gets a copy of Matty’s yearbook and discovers that she’s actually named Mary Ann and had assumed her friend’s identity…and lured her friend to her death in the explosion. One thing that’s interesting about the end of Body Heat is that Mary Ann has written in the yearbook that her ambition is “to be rich and live in an exotic land.” The last moment of the film is Mary Ann on an exotic beach. Normally, you announce a character’s ambition early on. But here’s an instance where the character’s true desire is as much a twist as the plot.

The Last Line

Last lines (and final images) are incredibly important. And, if you don’t believe me, think about all the last lines you remember. Just off the top of my head, here are some of my favorites: “Well, nobody’s perfect.” Some Like It Hot, “Do you remember where you parked the car?” Death Becomes Her, or from the wonderfully melodramatic Now, Voyager “Don’t let’s ask for the moon. We have the stars.” Your last line should be every bit as memorable while at the same time pulling together what your film is about. If you’re stuck, think about your opening image or line and consider completing the circle. If you’re writing a comedy consider ending with a joke. Making sure your audience laughs during the last moment of your film is a great way to make sure they leave talking about how great it was.

So, what are some of your favorite twists, last lines or endings that aren’t really endings?

      This makes no sense. Is something missing or mis-typed?

    Good article. Three things came to mind.
    1) A line from the 1999 song “Closing Time” by Semisonic : “Every new beginning comes from some other beginning’s end”
    In the context of the article it tells me that while your story has come to an end the characters in it are going on to a story of their own and the audience knows it. For example, a wedding at the end of a rom-com or straight romance. It gives them a good feeling and hopefully sends them off with a positive feeling about the script or film.
    2) A lot of films telegraph the ending from the beginning usually we can see the formulaic ending on its way. Or we see a different perhaps more realistic ending which may be put aside for the standard happy ending. Which way do we go is the question? My example for this is the lesser known but excellent, 1940 noir-ish Christmas film “Remember the Night” written but not directed by Preston Sturges and co-starring Barbra Stanwyck and Fred MacMurry. The film uses a framing device (which is a topic all its own) where it starts in one place sets the characters off and then returns. It would make a great double bill with 1944s “Double Indemnity” with the same stars and a framed story.
    3) Finally, I would recommend 2006s “Stranger than Fiction” starring Will Farell and written by Zach Helm, which is directly about storytelling and endings. People either love it or not but it definitely gives you lots to think about.

      Thanks for the comment! I actually watched “Remember the Night” a few days ago. And I remember “Stranger than Fiction” — it’s one of the few Will Ferrell movies I like.

    Usual Suspects (and just like that *poof* he’s gone) is probably my all time favorite. Really punctuates the movie’s intent to leave you dumbfounded at the end in my opinion.

    Can the last line in a horror film have a comedic line even if the moment itself is heart-breaking?

      Without reading the script that sounds terrific. Thinking back to the Scream franchise, horror is a genre that benefits from a bit of humor. If you can make me laugh and break my heart at the same time you’re doing great. Thanks for the comment!

    …I guess my favorite of all time big endings has got to be the final act of scarface…Right? however, i also thing The Shape of Water (an otherwise slow moving film) had an awesome third act.

      Thanks for the comment. Haven’t seen The Shape of Water yet, but it sounds interesting.
