motivated camera movement

at about 3:15 the camera moves from dicaprio playing with his kids, to the totem. even though the action is happening offscreen the audience knows to look at the spinning top on the table. 

in this scene we have the establishing shot of the underground scientific lab. The camera moves down to continuing the last shot to suggest that the place we are now in is beneath the place we saw before.

this scene uses camera movement as an introdution of an important charachter. at first all you see is a black and red blurr as the camera follows  rufio down the roller coaster still keeping him a bit obscured.
