After reading this news from Anime News Network,
yeah, reliable source of news...
I researched a bit more about it...
Yamamoto Yusuke will act as Suou Tamaki
Kinda Miyano Mamoru look-a-like?! O_O
Kawaguchi Haruna as Haruhi Fujioka
I hope the actress chosen has huge eyes just like Haruhi's LOL.
Definitely impossible to find in Japan.
