Given that there's also no chance it will be a good movie, this sets the stage for an even weaker stomach for any D&D offering.
It seems to me that "not be seen as a WoW movie" is a not-terribly-difficult marketing problem. I strongly expect the public will see Warcraft as less a "generic fantasy movie" and more a "CG movie", such that differentiation won't be difficult.
More difficult will be differentiating from LotR - and you might do that by having no orcs to speak of, and settings that don't look like New Zealand.
