I do not know why people keep saying '' never heard of them, looks like movie gonna be a fail etc etc''. Well first of all, Blizzard is well aware that movie of Warcraft is something that has been expected by its fans and they know that they cannot fail with this. It s not like the game, if you fail at something they will not have the chance to make it up by next patch. Some of u may say they can make second movie better (if they ll) but still, first movie will be in history of film making. Plus, considering this on a corporate way, movie must be a success so that it will bring more money and more players to the game or players BACK to the game.
Theses actors and actresses may fit or not, but one thing is for sure that they sure dig deep for the cast and still digging. Honestly, I prefer an actor/actress who is involved with the game or books rather than a huge star who is on top of his/her career and seek no new adventures and no idea about Warcraft. I believe once thet feel connected with the script they ll act way better than many academy award winner actors. Just be patient and stop being prejudiced. We will all see when it will release.
