Real actors were used!
You saw the Cyberpunk 2077 trailer, right? It was the talk of the Internet when it debuted last week, and a lot of people are really looking forward to the game thanks to it. Crazy, considering it was just a teaser and we may not see the game for a few years. That's the power of CD Projekt I suppose, and it does help that the trailer was really well done.
The trailer, more importantly, goes to show just how freaking passionate CD Projekt is. The team made a ton of concept art, and used real actors that were scanned to create the trailer alone. This posting over on Behance shows the entire process from start to the finished product.
Crazy how much work can go into just a trailer, right? If they're putting that much emphasis on that just imagine what Cyberpunk 2077 itself will be like.
