Although... skimom2, Grandma is with you. If Chris Hemsworth played Rocky, we'd go see it. Or maybe it would be a Girls Night Out for her.
I think it's to be on tv, not in theatres.
I can almost imagine Barrowman as Rocky but that's the only role I could accept a replacement for. The other original actors were too perfect for their roles to be replaced imho
Barrowman as Rocky would be excellent.
