Previsualization(Previs): term that is often misused to describe any technique that attempts to visualize scenes in a movie before filming begins.

"I think storyboards are great and do more than previz can do, and they do it in a form that everyone understands. No one assumes it’s exactly what you’re looking for because it’s a piece of paper, a static image. Animatics, while they sometimes stray dangerously close to the evil previz, are more like moving storyboards that can give you a sense of timing and, for people who look at storyboards and can’t imagine what the sequence is, animatics are OK. But previz has an aura about it because it’s so close to what they think you want. It moves, people change and look like they are walking; you’re moving through a virtual set, and it all becomes very misleading. Previz is banned from the Captain America world."

"There’s no hard Captain America news I can share with you right now. I’m really pleased with the team we’re assembling, though. We’re shooting in the UK, so we’ll be hiring some people over there, and I’ve got Rick Heinrichs as my production designer (he was also my production designer for The Wolfman). Shelly Johnson is shooting the picture, and Rick Whelan (who saved my life many times on The Wolfman) is my first assistant director. We don’t have an editor yet, but we’re pulling the team together. Stay tuned, though; we’re going to be assembling a tremendous cast."
