Madhouse (originally titled There Was a Little Girl and also known as And When She Was Bad) is a 1981 Italian slasher film directed and co-written by Ovidio G. Assonitis, and starring Trish Everly, Dennis Robertson, Allison Biggers, and Michael Macrae.

The film features a musical score by Riz Ortolani and cinematography by Assonitis regular Roberto D'Ettorre Piazzoli.

At the urging of her uncle, James, a local Catholic priest, Julia visits Mary, suffering from a severe skin disease, in a mental institution.

Sam visits her and tells her he is forced to take a business trip to San Francisco over Julia's upcoming birthday.

The landlord, Amantha Beauregard, passes by and offers to help him take a large bag; he tells her he is throwing Julia a surprise birthday party.

Once in the basement, Amantha realizes she has just helped James carry a corpse; he then chases her through the house and stabs her to death in the attic.

[7] Mick Martin and Marsha Porter of the DVD and Video Guide awarded the film three out of five stars, noting: "Although the story sounds simple, there are some surprises.

"[8] Ian Jane of DVD Talk wrote: "Despite the ridiculousness of the script and the mediocrity of the acting, Madhouse has enough gore and ludicrous set pieces to make it worth a look for slasher fans.

"[9] Tom Becker of DVD Verdict opined, "Little touches of audacity notwithstanding, Madhouse ends up being a mediocre chiller with some unintentional laughs.

He said most gore fans seek out the film simply because of the splatter sequence in which a power drill is used to kill a dog.
