Aliasalpha: Now I'd buy interactive movies if bioware made them, say a mass effect movie detailing the first contact war with the turians, make it interactive with the paragon/renegade interrupts and branch the story at a few major points and that'd be worth buying.
Cutscenes pulled from a game without context? No thanks
Yes, without context it would suck. But who is saying there wouldn't be context? Look at what Kotaku (probably selectively) quoted, not their fluff.
Kotick is basically saying, take the cutscenes, make a movie out of them. He doesn't say "take only the cutscenes".
I haven't played SC2, so maybe all the cutscenes are completely irrelevant and not linked in the slightest. But, for most cutscene heavy games, the cutscenes with minimal linking is all you really need.
Hell, I think one of the Metal Gear Solids actually DID do that as a way to recap a previous game (don't quote me on that though). Just show the cutscenes alone. You have a few disjoints ("How did Snake get on top of that building?"), but those are in most movies and TV shows anyway. And with minimal additions (maybe even just game footage), those disjoints are gone.
