I want to see Sheridan play any role anywhere (and I will probably go to London to do so). If people believe Sheridan should not play the role on Broadway solely because she's not American, they should start rethinking the casting of every role on Broadway, including the countless Americans in non-American roles. If Sheridan's wonderful in the role, it makes absolutely no difference where the stage is located. Xenophobia has no place in theatre or on Broadway.
She's very, very talented but it just wouldn't make sense to have a West End actress play the lead role in a revival that Americans have been waiting for for years on Broadway.
Which Americans? The only ones I know who have cared even a little bit are a handful of musical theatre fans. And even among them, those who have seen the show still don't find it to be very good. There is no hot demand for this particular show other than as a possible vehicle for a celebrity. Funny thing is, we've had plenty of those with a desire for Imelda Staunton to transfer to Broadway in Gypsy, but I guess that's okay because we've had numerous short-running revivals over the years. Are we just pickier when it comes to an inferior show that hasn't been revived (for obvious reasons)?
