The official French submission for the Foreign Language Film Award at the 83rd Academy Awards.

Once the screenplay was completed, it was sent to the relatives of the monks to receive their approval.

Features in the 2016 film "Me Before You" starring Emilia Clarke

Mostly shot in an abandoned monastery in Azrou, Morocco.

Included among the "1001 Movies You Must See Before You Die", edited by Steven Schneider.

In researching the screenplay, director Xavier Beauvois spent six days living at the Tamie Abbey in Savoie. All the actors were required to do the same as well.

The actors trained for a month under Francois Polgar, the former assistant director of the Paris Opera choir. This helped them sound more authentic when it came to singing Gregorian and Cistercian chants. Of the actors, only Lambert Wilson had any previous experience of singing, having performed in several one-man shows.

Stayed at the top of the French box office charts for four consecutive weeks.

When the film was released in the United Kingdom, it was only shown in 16 cinemas. Nevertheless it still managed to crack the top 15 films of the week.

With 11 nods, this received the biggest number of Cesar nominations in 2010.

Xavier Beauvois' second film to premiere at the Cannes Film Festival. His 1995 film Don't Forget You're Going to Die (1995) had also been showcased at the festival.

The monks of Tibhirine were kidnapped in late March 1996 and were found dead two months later. To this day, no one really knows who was responsible for their murders. While the Armed Islamic Group were the captors, in later years they claimed that the Algerian army accidentally killed the monks. The captives had all been decapitated with their bodies never having been discovered. Their remains are buried in the churchyard at the monastery.

Producer Etienne Comar got the idea for the film when the 10th anniversary of the killings was being talked about on French media.
