frame by frame...? may I ask how? :D
At the Game Trailers site, after you've finished watching the movie the regular way, it's still there, even though the screen is dark. At the bottom right are two arrows: >> and <<. If you press << briefly, it will go back one frame. If you get it to go back all the way, pressing >> will get it to go forward one frame. (That's how I got the screenshot for Raven and the one of the blue-eyed wolf.)
Seeing it all frame-by-frame reminds me of how much I like the intro and outro Geralt better than the in-game one. Oh, the in-game one is nice, just fine for a game, but his eyes look rather blank, whereas in the cinematics, there's somebody home behind his eyes.
