A Very Brady Sequel (1996)

The trusting and anachronistic Brady family gets a harsh jolt of 1990s reality when scheming con artist Trevor Thomas (Tim Matheson) shows up at their home, claiming that he's the long-missing first husband of Brady matriarch Carol (Shelley Long). Her real husband, good-natured Mike (Gary Cole), is none too happy about their house guest. The Brady kids eventually catch wind of the deception, leading to an antic-filled excursion to Hawaii when the impostor steals a prized family possession.
