Well, normally I would only see this as a com/net/org domain but in the case of .biz, maybe you could use it to sell dvd's and movies, like classic horror films etc. which is always a popular genre.
It's limited in use, but it has some potential if used properly. Still, I would not plan on a big return from your initial registration investment. This is a risky name in a risky extension.
Good luck.
