That depends on what you mean by "interactive movie". I've seen some games that rely too heavily on cutscenes, and other games that keep the character pretty strictly on rails (e.g. Call of Duty and Half-Life series), and I generally detest both of those.
I like to get into high tactics, if not strategy, in the FPSes I play, which means I like games that have the scope and openness for emergent action. Typical examples would be Far Cry and Far Cry 2 (but not Crysis, being spoiled by the suit's power). These aren't really what I'd call interactive movies, because even though they have plot to keep the character moving along, the main meat of the game is in how you tackle "action bubbles" - but those action bubbles are nice and broad that there's plenty of scope for deception, diversion, distraction, improvisation with explosives in the environment, and an openness to lots of different approaches that linear games like Half-Life (particularly 2 and episodes) can never really match.
I think Larrabee is a lot more promising than Itanium ever was. At the bare minimum, it's a server-like x86 processor.
I would prefer something with a more elegant ISA than an x86, but that's what we have in front of us now, thanks to the huge mass of non-portable x86 code that's so critical for success on the desktop...
One observation though, what is sold as a 'game' today is more of an interactive movie.
As to the larrabee, I can't wait until it comes out. That chip is going to give NVIDIA serious headaches.
Lots of good stuff in there, I just skimmed it will go back later to read it again.
