15 of the best movie prequels ever

Ginger Snaps Back – The Beginning (2004)

The previous entries in this werewolf series took place in the present day – but Ginger Snaps Back relocates the action to 19th century Canada, where sisters Brigitte and Ginger fetch up in a fort that's under siege from lycanthropes.

Where the first film used lycanthropy as a metaphor for puberty, this is a more straightforward period horror – but stars Emily Perkins and Katharine Isabelle are well-established enough in their roles that the change of scene is enough to keep the film ticking along.
