He could play the Beast in the next Beauty and the Beast live performance thing
He's got the voice, the 'ugly' scar.....and Katara can be Belle, healing the scar/curse and making him pretty/Prince again
(though he is still hot with the scar......oh well, i'm sure the writers will think of something)
(So maybe I've been watching lots of beauty and the beast zutara vids on livevideo
)
