I have a villain with a dastardly plan, I also have a character describing what the plan may result in. I would like that description to be accompanied by visuals.

Would I use parenthesis such as (POTENTIAL FUTURE), or would I use something like:

SERIES OF SHOTS -

Narrator (V.O.)
The destruction would be unparalleled.

A. The bomb explodes.

B. Buildings are crumbled, the dead and dying are strewn through the city streets.

-------------------------------

The only thing I found in the screenwriting manual I am using is "series of shots", what if I only wanted to show the bomb exploding in one shot? That wouldn't work either.

Thank you in advance.
