The whole controversy is a silly tempest in a teapot.  Natalie got her Oscar for acting, not dancing, so how much actual dancing she did shouldn't even be up for discussion.  Her body double is complaining because she was only credited as an "extra."  Well, Sarah Lane and/or her representatives should have negotiated the proper credit before she signed her contract, because that's where all that stuff is specifically spelled out.  Instead of whining, she should use this as a learning experience: DON'T SIGN A CONTRACT BEFORE YOU'VE READ IT.  EVER.

As far as Natalie and "amazing" go -- Idk. It sounded to me like she was not really prepared for the question (since she's promoting a different movie) and she really only said "amazing" once, so...I'm gonna give her a pass this time.  j/s
