I think the only way a revival could work is for them to bring in an unknown. No reality show BS either. The preconceived notions of the audience are gonna be with Streisand owning this part (which is why a revival hasn't happened yet). If you are to add a somewhat "known" actress to this, the whole production will be behind the 8 ball to start. This of course hinges on them finding the right "unknown" of course.
That being said. I believe in my heart of hearts that this is an un-revivable show becaue of Streisand in the movie and on Broadway.
Other than that, did you enjoy the play Mrs Lincoln?
