Nope. Don't see it. I'm sure they could find someone better, or at least of the same ethnicity as the character's name.
how do you guys do this? Go to IMDB, type a random letter in the search box and pick the first name that appears??
Sari Sumdac: 8 year old of Asian descent. Halle Berry: Grown woman who's black. Doesn't work. Why not Jessie Eisenberg as Buster Witwicky? He's got the hair down, all he needs is a pink shirt.
You mention Jackie Chan? Why? He's more awesome in live-action than his voice for a Transformer. Actually, someone tell MBay to cast Chan in TF4, it'd be explosively awesome! Seriously, who could Chan voice? "NO I don't want a grown woman portraying a little girl." And Sam Witwicky's family was into hardhats? Revision, reinterpretation, people! Open minds, please!
Have Tania.....whatsherlastname, the girl who voices Miko on Prime. She'd be a more appropriate Sari, assuming she was moved to highschool age.
