I agree, Madonna Musical, I do hope they get the word out there. For the general public though, there's no name recognition with Groundhog Day except for the title—and Bill Murray, who isn't in it. I think musical adaptations of well-known movies are a tough sell. As theater fans, we all know of Andy Karl and Tim Minchin, but they're not a draw outside of our circle.
I think shows cost so much to produce now, that there's not much left in the bank for promotion. Unless you're Scott Rudin.
