I think the only way it could work is if they went the full CGI route. Blizzard's cinematics team has created, by far, the best game cinematics ever and I always wanted to see more.
Here's a bunch of links to remind everybody just how great they could be -

A bunch of standalone WCIII clips (Arthas' coming home scene was always my favorite, the first time I visited the Undercity all I could think of was this scene.)

But Ceno is probably right, I mean look how bad they fucked up . I never played, but come on, how hard could it be to know that attaching a Waylans brother to your D&D movie is a bad idea?
