Based on V.C. Andrews' scandalous, incest-heavy gothic horror novel of the same name, 1987's Flowers in the Attic features what is arguably the creepiest attic ever put to screen. After the death of their beloved patriarch, the surviving Dollanganger family — Corinne, Cathy, Chris, Carrie and Cory — travel to Corinne's childhood home of Foxworth Hall to try and win over Corinne's estranged and extremely wealthy father. Expecting a warm welcome, the children are instead relegated to a little-used attic, where they are locked up until Corinne gets herself back into her father's will. Corinne's fanatical mother Olivia abuses the children mercilessly, until finally revealing that Corinne was cast out for marrying her uncle — their deceased father.
The children live in the attic for several years. Eventually, they discover their mother never planned to let them out at all, and has been feeding them arsenic in an attempt to secure her inheritance. This attic may feature a glorious view and be filled with all sorts of interesting things, but it becomes a prison, and, eventually, a grave for little Cory. The kids ultimately escape, but the trauma follows them for the rest of their lives. Lifetime adapted all four V.C. Andrews Flowers in the Attic books, but the 1987 film features the creepiest attic of them all.
