Channeling (Spirit) is probably the way I'd do it.
This. For the most part, anyway.
Channeling (Spirit) is a good way to go with the kinetic side of things that are shown in the movie (the talent show, teeth pulling, launching people/things, etc).
At the same token, you could also claim that any power the character takes, such as Wings (for the Flight side of the film) or even a modified Thaumaturgy/Evocation (weather changes and lightning bolts), are "powered" by the psychokinesis that the character acquired.
As far as I can tell, the powers are already there and anything could work; you might just have to change the "flavour" of it to fit the setting.
