The Wolves of Willoughby Chase is a 1989 dark fantasy film directed by Stuart Orme (in his theatrical directorial debut) with a screenplay by William M. Akers.

Like the book, the film is set in an alternate history version of nineteenth century England where wolves roam the countryside.

At Willoughby Chase, a beautiful middle-aged woman arrives: she is Bonnie and Sylvia's cousin and their new governess, Letitia Slighcarp.

The next day, Bonnie and Sylvia go out on a sleigh and are menaced by wolves, but Simon, a boy who lives in a nearby cave, rescues them.

They overhear Slighcarp revealing she has forged a copy of Lord Willoughby's will (with Grimshaw's help; he is a master forger and her ally) and prearranged the sinking of the Thessaly to claim his fortune.

Bonnie pretends to have gone manic after being in the cupboard too long, in an attempt to lure the local physician, Dr. Morne, to rescue them; the plan fails, and Miss Slighcarp burns a letter addressed to him.

They have to work in a laundry attached to the orphanage, with dangerous machinery that keeps breaking down - Sylvia is nearly killed after Rupert forces her to fix it from a very high and rickety catwalk.

Lord Willoughby gives Aunt Jane the mansion's East Wing, so that she has a place to live and Sylvia does not have to leave her cousin behind.

Unfortunately the album only includes cues of certain scenes while the rest of the score remains unreleased or incomplete; such as Letitia Slighcarp's arrival to Willoughby Chase, the scene where Slighcarp locks Bonnie in the schoolroom wardrobe, the dismissal of the servants, the introduction before the journey to Blastburn, the entire first portion of the chase sequence in the Blastburn workhouse and the final moments of the motorized sleigh sequence, among others.
