Prom Night - Watch Order: Mary Lou Films
This watch order focuses exclusively on the connected supernatural storyline of Mary Lou Maloney, the vengeful ghost who becomes the central antagonist of the series' only true narrative subseries. These two films shift the franchise from slasher territory into supernatural horror, following Mary Lou's haunting presence and obsessions.
Viewing just these films provides a narrative that stands apart from the anthology nature of the broader franchise. The duology explores Mary Lou's vengeful return and escalating supernatural chaos, with Prom Night III taking on a more comedic and surreal tone while continuing her story directly from II.

Hello Mary Lou: Prom Night II
When Hamilton High’s Prom Queen of 1957, Mary Lou Maloney is killed by her jilted boyfriend, she comes back for revenge thirty years later.

Prom Night III: The Last Kiss
Mary Lou, the prom queen burned to death by her boyfriend back in the fifties, has escaped from hell and is once again walking the hallways of Hamilton High School, looking for blood.
