I love Broadway and it is so nice to peruse the offerings on playbill.com. You can check out what’s playing on Broadway, Off-Broadway and in London. Free membership gives you access to discounted theatre tickets, restaurant offers, and merchandise. Playbill.com lists performance schedules, ticket prices, show run times, theatre information, advisories, synopsis, and more.
For more local entertainment, check out moviefone.com. Easy to use to fine theatres, titles and sometimes purchase tickets. There is a coming soon section and a new DVD release section.
Thanks to Kathy Leeds for these great suggestions!
