This was actually reported by Forbes a few days ago. Avatar is the only original film to have a larger gross. Everything else ahead of it is a sequel, prequel, based on some other source material, or an actual historic event. The Lion King and Finding Nemo other the two original films it recently passed. It's not often that an original film does this well.
The film is creeping towards 1B WW which is amazing considering no one thought it would get close.
