I remembered back then when the producers annouce the live action, they put up a notice to look for the actresses for this live action drama (cant find that source of info) Now, the live trailer is up and I took a peek at it. Perhaps it is just me as I am not used to anime/manga -> live action conversions, my hair stand when i watched the trailer. Some of the girls look awfully funny especially Nodoka. I have trouble identifying the girls in which character they are in but nonetheless, I agree with DigiGatou, Chachamaru and Negi are the the only people that I can recognise. Geeez -.-

On a sidenote, the actress for Negi is only 13 years old. Pretty much of a feat to act in the drama with that kind of hair.
