Gamebreaker TV, Actor WISHLIST
Ron Pearlman as Thrall
The ultimate Mary Sue or Warcraft needs a strong actor who can work through latex.
Ron Pearlman killed it in Hellboy and continues to be a tough guy in Sons of Anarchy. He would need to big and strong to be the shaman that saves Azeroth from Deathwing, but also sensitive enough to befriend humans and works towards diplomacy. Do you remember him on the TV series Beauty and the Beast?
Scarlett Johansson as Jaina Proudmoore

Jania Proudmoore started out being a lovesick daddy’s girl with a penchant for princes. She always had her head in a book and did what she thought was right for her people. After her city was nuked, the most powerful mage in Azeroth started dating dragons, hating orcs and setting her sights on revenge.
Scarlett Johansson can go from nerd-girl to action hero in a heartbeat and would be perfect for this role.
Duane Johnson as Garrosh Hellscream
Sure he might be good as Thrall, but why not Garrosh? I hate to see
The Rock as a bad guy, but if we go back to Nagrand and find the future warchief on his home turf, we might be able to get a taste of the good orc he could have been. Who am I kidding? The apple didn’t fall far from the tree.
Johnny Depp as Vol’Jin

Warchief Vo’Jin is a bit of a zaney character that could use someone with acting chops top to pull it off. Of course if we got our wish the troll would probably be portrayed a bit differently than we imagined.
Johnny Depp as Hunter Thompson as Vol’Jin. It’s hard to picture the character with a cigarette holder, but it could work.
Tom Cruise as Varian Wrynn

Hear me out! Remember the Last Samurai? Bring THAT
Tom Cruise into the Warcraft movie, tell him to channel a wolf and there you have it.
Benedict Cumberbatch as Lor’themar
Not now
James, we’re busy. Wait, that idea makes sense! Khan would make a perfect Blood Elf leader! He’s skinny, has intense eyes and can portray the arrogance of the leader of the Belfs perfectly. Do you think Lor’themar is upset that he isn’t leading the Horde? What do you think
Cumberbatch would do about it?
Chris Helmsworth as Arthas

Several people tweeted this to me and it isn’t much of a stretch, but I still like it. Not sure if
Helmsworth would want to play another fantasy character, but this is his shot to break bad. Watching him slice through civilians at Stratholme, tear the soul out of the body of Sylvanas and raise the dead to take over Silvermoon might anyone rethink this golden boy.
Xun Zhou as Tyrande

I’ve long been a proponent of the idea of
Night Elves being Korean. This gives us the perfect opportunity to get a renowned Asian actress into the Warcraft movie.
Xun Zhou wowed us in Cloud Atlas, and she is so popular that her presence in the film would guarantee a large Chinese audience.
Michele Morrow as Sylvanas
It’s no secret the actress has been vying for this role for a while now, and I think casting an actual WoW player as the Banshee Queen is a great idea. The PvP fan has the archery, has the bod, and has the leather. This one is a vote for the home team.
Ian McKellen as Khadgar
I’m not sure if Khadgar is a likely addition to the Warcraft movie, but this is a great idea. He is Gandolf. He is Magneto. He could be Khadgar. Get over it.
