Meet the Hollowheads (1989)

The Hollowheads are a normal, loving, futuristic, middle class family who live in a dystopian, corporate-controlled, The Jetsons (1962)-type future world populated with many cool gadgets and some alien creatures. Henry, the pacifist head of the family, is hoping for a promotion at the slime factory where he works, and when his sleazy boss invites himself to the Hollowheads family dinner, Henry mistakes this for a sign that his moment has finally come. However, when his boss shows his dark, horny, perverted and rude side at the dinner table, and crosses all the lines when he starts verbally abusing Henry and sexually harassing his lovely wife, the family has no choice but to come together and fight back.
