Know What's Out There! That's where a site like ours can help. However, if you really want to do some serious digging, consult with either the Internet Movie Database or (if you'd rather go the print route), Leonard Maltin's Movie Guide, available at your bookstore. In fact, you'd be amazed at just how much information you can excavate on B-movies just by going to your local library.
But if you'd rather go the high-tech route, there are more than a few websites out there on the World Wide Wait that devote themselves to B-grade cinema; we've listed a few of the best ones on the Nanoscope part of our site. Happy hunting...
