So we'd start with the Book writer, Hunter Bell, played by Prince Harry. Clearly we're going for a younger demographic with this casting.
Then we have the song writer, Jeff Bowen, played by Patrick Wilson. These two guys look so much alike it's freaky.
Susan Blackwell, played by Holly Hunter. Both handsome ladies.
Heidi Blickenstaff, played by Renee Zellweger. I happen to think that Heidi is prettier though...
Musical director and "orchestra" Larry Pressgrove played by an older Ed Harris.
The "director of the show," Michael Berresse, would be played by the amazing Jake Gyllenhaal
