Film Deaths[]

David and Lisa (1998) [Maggie]: Decapitated with a giant clock hand by Lukas Haas in Lukas' dream sequence. (She survives the movie in reality.) (Thanks to James)
Frogs for Snakes (1998) [Simone]: Shot in the back by Justin Theroux as Debi is about to shoot Lisa Marie.
House on Haunted Hill (1999) [Jennifer Jenzen]: Her scenes were deleted from the final cut, but in one of those deleted scenes, she is being led into the titular house by a real estate agent (later revealed to be Jeffrey Combs), and screams a few minutes after entering, indicating she was killed.

Happy!: The War on Easter (2018) [Isabella Scaramucci]: Stabbed in the side of the head by Antonia Rey as her brother (Ritchie Coster) looks on. She later appears again when Richie sees her and the rest of his family in Hell.
