Some writers will say that any instructions for directors is bad, while others will say some is okay.  Again, don’t look to professional screenplays for the answers because they aren’t spec scripts; they’re more than likely shooting scripts.  When you write a spec script, you want to keep the camera out of it. 

The purpose of your script is to tell a story and to keep the reader engaged. If you use the phrase “We see” over and over, you pull the reader out of the experience.  Take this phrase out of your vocabulary immediately.  I don’t care if you see it in professional scripts or think it’s cool, it’s amateurish and you can be more creative than that.  Your repetitive use of “We see” is taking up valuable property on your script.

Eliminate all your ‘cut to’ and ‘smash cut to’s.  This is directing the director.  This is old formatting and isn’t used any more.  The only time you ever refer to cutting a scene is if absolutely necessary in getting across a certain visual style.  If you are matching cuts or have a clear style throughout the rest of the script but this particular scene should be cut differently to make a clear point or impact on the viewer. 

Pans and dollys are also camera references.  If you can’t find any other creative way of explaining how this shot is to look, then use it.  Even so, these should be used scarcely, meaning once or twice in your whole script.  Overuse of any of these devices only shows your inexperience. 

The only way you can direct the director is by being creative and specific with your craft.  Remember that everything you put on the page will be shown on screen so if you want a shot to look a certain way, you have to describe it that way so the director sees it the same way you do. 

For example, let’s say this is your fight scene:

Jane kicks Sidney across the room.  Sidney whips a vase at Jane.  It flies out the window.  Jane and Sidney run at one another screaming.  They lock arms and spin in circles.  Jane throws Sidney through the window.

But this is how you want it to look:

Jane kicks Sidney in the gut.  She flies across the room.  Sidney grabs a –

VASE

It flies across the room, narrowly missing Jane’s head, flying through the window.

JANE

narrows her gaze at

SIDNEY

who glares back.

BOTH GIRLS

charge at one another screaming.  They lock arms, spinning in circles.  The room spins with them.  Until

SIDNEY

is sent flying through the window.

This is pretty controversial because you could argue that they’re the same.  The second option takes up a lot more real estate and is kind of annoying to read, but it’s certainly clear what your intentions are.  My point is, if you want to have absolutely no doubt that this is how the scene should look, write it the way you see it.  I would, however, seriously think twice before writing your whole script like the above example.  It’ll end up running 200 pages and no one will read it.
