Yes Hollywood is losing money, Yes they are making lower budget films in places where the taxes are less (Canada.) And yes they are using fewer big box office names (Sean Penn, Danny Glover et al.) Yes they make more money outside of America than in.

But maybe it's time they looked at the audience they no longer have and it might add up that they are losing money because they no longer make movies AMERICANS want to see!

Halo is a good example of what happened when Microsoft was unwilling to let Hollywood have too much creative control over their premiere franchise. Hollywood backed out. While I still hope to see a good Halo movie, I much prefer that Microsoft back out of the deal then let Hollywood ruin it.

I imagine Call of Duty will be much the same. As will the World of Warcraft movie. At this point, those video game franchises are way more valuable than most movie franchises. As a result, the companies that own them (Activision-Blizzard & Microsoft) have a vested interest to not let Hollywood mess them up.

Those previous franchises that you mentioned had little to lose and lots to gain from the exposure of a major motion picture.
