Blood Theatre (also known as Movie House Massacre) is a 1984 American independent slasher-horror comedy film directed by Rick Sloane and starring Mary Woronov, Jonathan Blakely, Jenny Cunningham, and Joanna Foxx.

To motivate his employees, he offers a $1,000 bonus that will go to one of them after a test run, much to the chagrin of his incredulous assistant, Miss Blackwell.

During a screening at the main theater, Selena, a disgruntled concession stand employee left out of Murdock's promotion, causes a scene, and is escorted out by Miss Blackwell.

Meanwhile, Lisa and Dee-Dee, two other Spotlite employees dropping off the contents of Jennifer's old locker, are attacked in the auditorium and stabbed to death.

The next day, while Jennifer, Adrian, and Malcolm are in the office, Darcy becomes locked inside the auditorium and is attacked and dragged underneath the stage.

Selena arrives panicked, looking for Darcy, but Adrian sequesters her in a locked room to avoid a scene in front of a local news outfit doing a story on the theater's reopening.

On the other end, Miss Blackwell hears Selena's screams before the phone receiver inexplicably crumbles in her hands.
