Storyboarding and visual references are always good. But if you watch enough BTS videos, you'll find that the storyboarding is really a reference, and people change things on the scene all the time based on the particularities of a location or weather or whatever.
Edit: I didn't storyboard my last film, but it went just like I wanted it to. Because I took my DP and my actors to the sets. They saw the location. We discussed scenes on the location and where the cameras were going to be, where the lights were going to be, where the actors were going to be. They had a better picture of what I wanted because of location meets. Much better than storyboarding would have achieved.
The Matrix is perhaps a unique case where it
was meticulously storyboarded, down to character likenesses and costume detail. And because they wanted to emulate a particular style of shot design, the Wachowskis
had to have storyboards in order to make their shots turn out exactly like they were in their heads.
Other films will approach storyboarding in a similar fashion. Yes the locations may change on an Indie production, and some locations will be dropped simply due to weather. But that's part of the reason why you shouldn't get too exact with the location design in your storyboards.
Storyboards aren't just for figuring out blocking within a specific space, they are also for figuring out the emotional and psychological purpose of each shot in a sequence and scene. And many times, if you don't try to storyboard and work out shot design before hand, then the visual style and design of your film might not project and express what you want it to convey. You have far less of a chance to think creatively about your shots, and you might not easily consider different alternatives unless you're just really good at making things up on set. I do think every director
should be able to make on-the-spot changes to shots while on set if a situation calls for it. But trying to create an entire film on the fly is not only risky and perhaps reckless if you are working with a decent amount of money and people's time, but it can also vastly reduce the potential quality of the overall film because there is no tangible structure that everyone can look at for how the film is supposed to look.
Now in some cases, you might not be able to storyboard at all due to a lack of artists at your disposal, lack of artistry yourself, or simply a lack of time, like in my case. I've always
wanted to fully storyboard a project, but my deadlines have always been based on school assignment due dates, and so I've never had the freedom to meticulously storyboard something, and perhaps even construct an animatic. But the next time I start creating a film, that's exactly what I intend to do.
However, the last time I
did try to storyboard, I realized I wouldn't have the time to draw it all, so instead I wrote out all of the shot details on a large shot-list document, with field boxes for every aspect and descriptive element of the shot. Where the camera was, where it was looking, the general length of the lens, the center of focus, the camera's movement, the character's blocking, and anything else, in order to properly design what shot will lead into what, and what sort of progression I wanted each scene to have.
It's called a Verbal Storyboard, and I would encourage anyone who doesn't do one already to consider making one if you aren't much of an artist, because it can really be extremely beneficial to the way you construct your projects.
