From Pixar's 22 Rules of Storytelling, brought to my attention through the kind offices of +Ksenia Anske :
A. Once upon a time there was ____.
B. Every day, ____.
C. One day, _____.
D. Because of that, ____.
E. Because of that, ____.
F. Until finally, ______.
If there is a better condensed story template out there, I haven't seen it.
Here is how it was used to pitch FINDING NEMO:
(But note that C is the transition between Acts I and II, so it seems to me to belong in both Acts.)
Act II is sentences C, D, and E. Notice that the pitch above switches to present tense to mark the transition into Act II.
Act III is sentence F.
Now to see if my novel fits. (Or make it fit, dammit.)
