Dude, a lot of that was clearly in game :)
For example, the guard getting hit by a barell and falling over... those animations were definitely part of a game's physics engine. You wouldn't animate something that idiosyncratically just for a cutscene... well, maybe team ICO would, since their cutscenes become their gameplay at times...
But really, the kid's animatons seemed clearly controlled at some points in the movie, while in other parts, like when the griffon is coasting through the water and the boy jumps off of him, it seems more like animation just made to look good, which you wouldn't control.
*edit* of course, even if it were in-game, in-engine, etc etc, I suppose it could still be doctored up for the trailer. But for, only time will tell. Have you seen the horse in shadow of the colossus? It's probably the most photorealistic thing on the PS2.
