Emma Watson Mouths Everyone's Lines in the Harry Potter Movies

Just found this on YouTube of an early screen test for "Harry Potter and the Philosopher's (Sorcerer's) Stone" where Emma Watson, Daniel Radcliffe, and Rupert Grint rehearse a scene from the movie for the first time.  The cutest thing?  You can watch Emma mouthing the lines of both Dan and Rupert, as well as being able to deliver her own lines.  True to Hermione...always ♥
