Jim here. Looks like Leona Lewis has the AVATAR closing credits song wrapped up. The song is entitled I SEE YOU.She will not be alone for the performance. Oscar winning James Horner and Simon Franglen are producing; these are the same guys who helped Celine Dion on TITANIC's MY HEART WILL GO ON. Horner is of course delivering the movie's score.
You may remember Lewis from winning X FACTOR.
Leona should help bring in the female demographic and underscore the romance that is embedded in the special effects.
