in the old animated version, the voice of Hercules is done by Ricky Martin (idk if you even know him xD) and the thing is that at that time, people said that if there was a live action of Hercules, he was a really good fit (?)
anyways, disney being disney I'm pretty sure they be'll hiring Choi Woo-shik, or Whoopi Goldberg as "according to them" the perfect fit
