One of the hot links at the top of my firefox browser is IMDB, because movies also tweak my interest. It is always good, when having a disagreement about someone's role in a film, to bring up their page and settle the argument once and for all.
Broadway shows? I don't think I'll ever have a dispute over where a show played, how long it played, who was in the cast and what they moved on to. It's just not interesting to anyone else I know.
Apparently, there are others who share that bug for theatre, because there is a counterpart to IMDB. It's IBDB, the Internet Broadway Database.
I've learned some cool stuff...
*the first Broadway show I saw (The Magic Show, Cort Theatre, July 28, 1976-yes, I know the date) had David Ogden Stiers in a very minor role
*the cheapest ticket (2bucks for House of Blue Leaves, Vivian Beaumont, May 2, 1986*) worked out to pennies per name star in it-Danny Aiello, John Spencer, Stockard Channing, Swoozie Kurtz, Ben Stiller, and Julie Haggerty. The reason why it was so cheap was that the theatre department chair was a college buddy of one of the producers.
*the most compelling storyline (Angel's Fall, March 1983) was a show that only ran for 57 performances
