A rumor has been started online that
Alexandre Desplat and John Williams
will work together on the production
of various tracks for the soundtrack of
"Harry Potter and the Deathly Hallows: Part Two".
We did previously recieve confirmation that
John Williams will return to Harry Potter 8
somehow, but may not be the main composer
for the various music themes in the film.
Now it appears that he will return and assist Alexandre Desplat
in the creation of the HP8 soundtrack. So although he may not be credited
on the soundtrack's front cover, we can now be sure he will personally
be involved in its making. We still await further official information,
which may not be announced online for a few months.
