Is the giant white bird in the recent animated SInbad film meant to be a Roc?

I read the stories a long time ago, and quickly realised the animated film ';Sinbad: Legend of the Seven Seas'; is only loosely based on them. There's a giant white bird that arrives with snow and ice - is this ever referred to as a roc in any of the commentaries or interviews etc? I'm sure it's based on one, but I'm just curious. Many thanks!Is the giant white bird in the recent animated SInbad film meant to be a Roc?
I don't know google it! i've seen the film though and that scene scared the crap out of me!(hey when your young you tend to be more easily surprised)
