I haven't seen this film - [[http://uk.youtube.com/watch?v=CRSL4b_N7BQ only this clip] but from the discussions on the Floortime list I think you'll like it.
DS1 was very like the little boy on the clip at that age.
My opinion is that it doesn't matter if you call it autism providing someone remember to think about sensory processing - but that often gets forgotten.
