A post on a forum not too long ago discussed how important it is to give the audience a hint ahead of time to show how it's possible for a protagonist to extricate himself from a crisis or dangerous situation. He/she/it (can't remember) suggested that it's critically important that, even if only for a second or two, the audience sees that there's a way out or at least the potential.
I think this was specifically aimed at action writing but I'm not sure. Doesn't matter. I wholeheartedly disagreed with this premise regardless of the genre and, after a month or so of watching action films and reading scripts to explore the idea, I still wholeheartedly disagree.
It's not that I oppose giving the audience a hint that Richard Kimball might escape through a storm drain or jump off of a damn or viaduct or whatever that was, I just don't think it's critical or required in every escape scenario.
In some cases, sure, give the audience a hint. IF IT WORKS. The word "escape" reminds me of a scene in Finding Nemo where Dory and Marlin are fleeing from a shark who fell off the "fish are friends" wagon. In that scene, we do get a clue, a hint, a jab in the rib right before they escape. Dory's inability to read the word "escape" was both a comic element and a message to the audience that there is a way out. That may be particularly important in this case considering the young age of much of the audience and the need to keep it scary but not too scary.
But in film, we like to surprise the audience and the audience likes to be surprised. If we aren't careful about things like this, we'll get the ol' "it was so predictable" slap. None of us likes to be told what we wrote was predictable. That's like saying we wrote something flat or prosaic. One or two scenes where we see "it" coming could spoil the whole film experience for the audience.
That's not saying that it WILL. I'm saying that it COULD. There are some crisis situations where if we DON'T give the audience a hint, it may not make sense to them later or it will feel like a contrived deus ex machina.
I'm taken back to what my grandmother said about showing only a little ankle to make the eye want more. She wasn't saying we should always show a little ankle or never show more than an ankle. She said that IF you're gonna flash skin, don't show too much. I'm not saying we should never give the audience a clue, just that it is not always necessary.
Of course my grandmother also said "never show your cellulite until you're wearing a wedding band". I don't know how to translate that into film...
