I'll start this by saying basically, we post some of the other characters in anime our voice actors in Naruto played.
I'll go with Hinata:
English Voice actress: Stephanie Sheh
Megumi in Digimon Data Squad
Penny in Zatch Bell
Orihime Inoue in Bleach
along with Naruto's Sexy Jutsu, Tsuchi Kin(sound chick Shikamaru fought in the prelims), and Hanabi Hyuga.
Japanese Voice Actress: Nana Mizuki
Unlike the english actress, Nana has been in much less and far more obscure animes.
