Y Tu Mama reference in PoA

[Mandy]

I loved they way Curon has begun to bring teen sexuality into the 
film, with the funny and obvious allusion in the beginning with Harry 
hiding under his bed sheets in the middle of the night playing with 
his wand, and the wonderfully satisfied grin on his face after he 
finally was able to successfully produce 'Lumos maxima'.  The sweet 
Ron/Hermione hand holding moment.  And the parallel between Ron and 
Draco, both milking sympathy from Hermione and Pansy, by telling them 
that their respective hand and leg might be in need chopping off.  

But that aside I have a question about the delightful moment in the 
film when HRH are standing on top of the hill about to watch Buckbeak 
get the chop.  Hermione buries her head in Ron's shoulder with her 
arms around his neck, and Harry gently puts his arms around Hermione 
and then the three of them hug in a very tender way.  

Is this is a nod to Curon's film Y Tu Mama Tambien?  I know that Y Tu 
Mama is a story of seduction between two teen boys and older woman, 
so it would fit, and Curon seems to be naughty enough to do something 
like that.  Who out there who has seen Y Tu Mama help with this one?

I'm renting the DVD this week, but I'm curious to see if anyone else 
has noticed this.
