Jason -- do you mean RE-cast the narrator? (not being snippy)
I don't think the role of the narrator is all that difficult a character -- I think we'll find that the humor of the role doesn't nearly as much as from the actor but the writing and direction.
And we don't know if she was passed over or (for some reason) the actress turned it down.
If we're not having fun, then why are we doing it?
