I was checking what languages it has lol. Japanese too but I like it in English cus I like Robin Williams he was a good actor. He said they let him do anything he wanted, and he did like 8 hours of stuff and they used what they liked for the movie ?? Caesar salad ?? ?? Bee ?? yourself He didn't write the song ofc but all the speaking is just him improvising He didn't have a script he's just told what the scene is and he made up lots of jokes etc and so the animators just worked with what he did Yes it's based on old stories called Arabian nights
