Troubled Production/Anime and Manga

Paranoia Agent: the production of an anime series is increasingly troubled by Executive Meddling, staff infighting, deadlines approaching, supernatural bad vibes everywhere, and the sociopath killing everybody related to the production.
The school film directed by Haruhi Suzumiya. Among the things going wrong are a cast of amateur school kids doubling as equally inexperienced filming staff, the main actress developing eye powers, doves changing colors, a cat gaining sentience and speech, and Haruhi taking her usual self to higher levers of jerkassery. That they had an actual video at the end of such a disaster of a filming to exhibit at the school festival was a little miracle by itself.
