Filmmaker Lars Janssen filmed André at a variety of locations which featured in the original film to “reinterpret” some of the key scenes, including Castle Cornet and St Martin Parish Church.
He also interviewed “about 20 people” who were involved in the 1975 film over a two month period, he said.
Janssen said he spoke to people including a pet owner whose dog was used in the film, as well as carpenters who worked on the set, firemen who helped create fake snow, and even an actor who was cast but then rejected by the director for being “too tall”.
While most of his film had already been edited, Janssen still expected not to get “much sleep” before the weekend, as he put the final touches to the film.
Laura Harrison, operations manager at the Victor Hugo Centre, said the documentary – which the centre commissioned – would be shown on Saturday 6 September as part of a programme of events to celebrate the anniversary, external.
She said the event at the Princess Royal Performing Arts Centre would also have talks from experts, followed by a screening of the feature film.
Tickets cost £25, plus a booking fee – but free tickets were available for local students, she added.
