For some reason I'm leaning towards Emma Watson or Dakota Fanning. I don't know that many Indian actors, but without taking nationality into account, the two I just stated might be at the right age to play a teen Sari. I think Abigail Breslin would be good as well for a young Sari. An alien robot, raised to be human, then finding out her own kind has come to live next door. I think she would be a great addition, since she's a character who is still in the road of discovery about her kind. Optimus Prime and the other autobots would already know about their history. Humans like Sam on the other hand are human and would be less invested on discovering Cybertronian culture and history since he's not Cybertronian. A character like Sari would have to be very invested on the other hand since she's Cybertronian while still being invested in her adopted world because she was raised as human. Well, I just wanted to throw it out there. I think Sari could truly be an interesting addition to the movie franchise. What are your thoughts?
