1.) It's Disney
2.) It's coming off a well-received run at the Paper Mill, a theatre that many people who regularly go to Broadway go to or at least know of.
3.) The movie does have tremendous appeal to a lot of people in their 20s. I'm in my early 20s and Newsies was one of my favorite movies as a kid that actually began my interest in musical theatre. I know many others who feel the same way.
4.) Jeremy Jordan's definitely being talked about. No, he isn't a huge star that will draw in crowds yet but a lot of people like rising stars so they can say they saw him before ... and I think that definitely applies here.
5.) Alan Menken is known for his consistent, enjoyable, and popular scores. The Newsies movie score is popular and in my opinion, one of Menken's best.
6.) It's really the only explicitly family-oriented show opening this season. If I'm a tourist family that gets to see maybe one or two shows a year and I want to pick something new, no doubt in my mind I'd pick Newsies.
7.) Word of mouth has been consistently good. Yes, I know the show has some detractors here but the buzz has been overwhelmingly positive in other circles: Twitter, Facebook, and yes, the water cooler.
8.) It was announced as a limited run. Though I and just about everyone else here were expecting an extension, when tickets were initially released, I think there was a bit of a rush among some people to try to secure tickets.
9.) Did I mention that it's Disney? Despite a few flops (Tarzan and the Little Mermaid), most people associate Disney Theatrical with its hugely successful productions: The Lion King, Beauty and the Beast, and Mary Poppins. The brand name gives people a sense of comfort as whether or not it's true, they expect a good value, high quality production and can be rest assured that it's squeaky clean and enjoyable for the kids.
