Hand-flapping?

[Wanda Sherratt]

I read back over the previous threads, but I couldn't find the 
original one that mentions that Daniel Radcliffe flaps his hands 
when excited.  Is there a moment in the movie when that happens?  
Someone said he does that in real life too.  I find that very 
interesting, because I have autistic kids, and it's a standard 
symptom of autism-spectrum disorders.  I was struck by Daniel saying 
that he'd like to study autism, and making the cd-rom for autistic 
people to help them learn to read facial expressions.  It's an 
unusual interest for someone so young. I wondered if he knew someone 
with autism, but now I suspect he may have a touch of Asperger's 
Syndrome himself (it's almost like a very mild form of autism).  It 
wouldn't be surprising - it seems a lot of people who go into show 
business have a bit of this, and acting seems to provide a place 
where their strengths can work, and their disabilities aren't so 
important.  Anyway, if anyone can tell me where some hand-flapping 
occurs in the movie, I'd love to know, and will watch for it.  For 
me, it's just another reason to like Daniel, who seems like a very 
sweet boy.
