Cursed Part 3 (2000)

A horror comedy that spoofs the narcissistic film director whose delusional vision of her badly written three page treatment (a direct ripoff of The Blair Witch Project), pages she feels are enough to make a complete movie. The director immediately loses its star (Donna Mills) and has to step into the female lead role herself. Not an actor, a beauty, or even a very good director, she is forced to face her limits.
