Here is the latest PV trailer for the new Pokemon Movie 2008 based of Diamond and Pearl. Moetron has also compiled a list of seiyu playing the characters. Used to watch Pokemon when I back in animation school and had a few friends crazy over collecting the games too.

Leila (*played by Akira Minami)

Mugen (*played by Yamadera Kouichi)

Infi (*played by Nakagawa Shouko)
