Cut Throat (2001)

When the lead actress is murdered on the set of a low budget slasher, things go on as usual. You'd expect that people would have some reaction, but since they think they're working on the next Scream, no one cares much about the deaths occurring on set.

The filmmakers are out of money, and things keep going wrong. But they still cast a new lead actress who gets her dopey friend a job. More murders and strange things happen, and still no one particularly cares.

This isn't very interesting, and certainly not original.  Probably a good idea to skip this one.
