Playbill.com is one. This is some of the absolute latest info on Broadway shows and actors, as well as theatre job listings. I'll probably highlight some stuff from here at times.
The Internet Broadway Database is another. This is a pretty comprehensive listing by actor and by show... very cross referenced. This is a great reference source sometimes!
In May, I'll be checking out info here on the Tony awards. This is the official website that lists current and past winners and nominees. There's even video clips from past telecasts!
There are a lot of specific theatre websites as well. Usually they list company members, current shows, past shows, audition notices, sometimes even staff or board members. In the next few weeks, I want to fill you in on some local stuff coming up... Stay tuned!!
