I like rules, but not as a rule. I like rules that make sense, that have a reason for being, and actually make things better. Like stop signs and no double-dipping.
One of the most talked about rules in screenwriting is what does – and doesn’t - go into the action lines.
Some writers are never tempted to put such things into their action lines as “She feels sad.” “You can tell these two have a strong connection.” “What did he just say?” or “He has never met this person before, but he likes them immediately because they remind him of a friend he had as a kid.”
Then again, some writers are.
The general industry-held rule is simply this: Nothing goes in the action lines that can’t be seen or heard onscreen. Period.
The action lines above, and their kin, are emotional states, interior monologue, and a serious case of TMI.
Now, this is a rule just like any other rule. The people who are tempted to put this kind of thing into their script will find all kinds of exceptions to this rule and justifications for it.
However, I happen to think this is a Very Good Rule for a few reasons I’ve found to be true over the years. They are:
1) Going against the rules can be enough to turn a reader off your entire script. Just like that. Even if they never come out and say so in the coverage, or tell you directly. Even if they’re not completely aware of what’s bugging them...this can be the thing that makes them decide that your script is unprofessional and poorly executed, even if it’s great in many other ways.
Why give any reader, from intern to Executive Producer, a chance to dismiss your script out of hand for something that is totally within your control to change? If you can make it “industry standard”, why wouldn’t you? It’s a standard as three-hole-punch paper with only two brass brads. And really...it’s the polite thing to do. It shows a certain lack of respect to not do it, or worse, a lack of knowledge. Enough said.
2) If there is no specific action attached to the interior information, there is no way for that to happen onscreen. We have to either see it, or hear it. If you want someone to express feelings of sadness but don’t create a direct way to do that, chances are you’ll get a performance out of an actress who’s thinking the hell out of “I’m sad”, but it could look just as much like “God, I want that man” or “I should really switch to cloth shopping bags”. No one will know what she’s thinking just by her thinking it.
3) If it’s important enough to be part of the story, it’s important enough to have a specific action created for it. There’s a high probability that without a direct visible, physical action to show the internal information, it’s just not going to make it into the picture.
Actors interpreting a script look for “playable” moments, and those moments will all be attached to some kind of action, even a movement or gesture. “He places a hand over hers before turning his eyes to her” shows tenderness and concern.
And, hey, if you don’t feel like making an action to show that idea, just cut it altogether. There, that was easy.
4) Give them what they need to see it when they read it. Non-visual action lines leave up to the reader - be it actor or suit - carte blanche to interpret those action lines however it occurs to them. They could be reading “These two have a connection” and imagining anything from a deep, soulful look...to a full-on, tongues and all, make-out session. Or worse, absolutely nothing. Make sure people are reading your vision of the story:
.........................
The one exception to this rule...yes, I get to make one...is when first introducing a character. It’s totally within reason to say a few choice words about a character that are background or emotional qualities, especially if knowing them right away will help the whole story make deeper sense to the reader. For example, a “real survivor” or “a former Beauty Queen wannabe”, describe an impression more than a physicality, but are evocative of a meaningful character trait. It’s still best to keep it simple here, but feel free.
The only argument I occasionally entertain is if a writer is going to be directing their own piece, and therefore will have all the inside dope. But please don’t fall into this. Other people have to read your script and get it. Actors have to read your script and play it.
IN THE END...Film is a visual medium. “If it ain’t on the page, it ain’t on the stage.” Yadda Yadda. There’s just no good reason to break the action-line-rule, and some very good reasons to follow it, all of which will make your screenplay more effective...and hopefully get made.
