From what I understand, ten cast members were not given the option to renew their contracts; nine were. Eight accepted and have renewed their contracts, and the ten that were not asked back plus one that chose not to renew will not be returning.
My best guess for the reason as to why most were not asked back is attendance. This is not the kind of show that relies on names. What is most important to the producers is that whomever
is listed in the Playbill as playing a particular role is
there eight times a week performing and that the understudy board is empty as much as possible.
Audiences in general are disappointed when they see names on the understudy board because they feel like they're missing something or they're being cheated somehow. No matter who is in the cast -- if they are there performing eight times a week -- audiences will be happier and they will be more likely to report positive experiences to their friends (future ticket buyers).
