Story without spoilers

The film follows Lucien Castelnau, a filmmaker whose ghost is released after a century inside a glacier. He then wanders across a futuristic Patagonia, confronting a society shaped by technological progress but disconnected from forgotten histories.

Lucien cannot find peace while his cinematic legacy remains unseen. His search is therefore both personal and artistic: he is looking for a place in history and for an audience capable of bringing his lost work back to life. The supplied synopsis presents Erratics as a documentary built around memory, disappearance and the continued search for spectators.

What to expect

Erratics is identified as a documentary, but its premise uses a ghostly central figure and a futuristic setting to explore the fate of an unseen filmmaker. Viewers can expect a story grounded in Patagonia, with French- and Spanish-language elements and a focus on the tension between technological progress and forgotten stories.

The film’s 92-minute runtime gives the concept room to follow Lucien’s search through this altered world. Its central question concerns what happens to artistic work when both its creator and its audience have been removed from history.

Cast and creative team

Denis Lavant plays Lucien Le Saint, the listed central cast member associated with the film’s ghostly filmmaker figure. Daniel Muñoz is also part of the cast, although no character is specified for his role.

Thomas Woodroffe directs Erratics and co-writes it with Valeria Hofmann and Antonio Luco. The film’s credited creative team combines its documentary format with a fictionalized premise centered on a filmmaker searching for recognition after being forgotten.
