Bliss (1985)

After Harry Joy dropped dead... his life was never the same again.

An advertising executive dies and goes to hell... except nothing changes. Well, his daughter is buying drugs with sexual favours from her brother, and the number of cancer-causing products is on the increase. But the notes he writes to himself to prove he hasn't gone insane are getting more disjointed, and he runs off with an ex-prostitute called Honey Barbera.
