It is based on the work Lost Splendor by Felix Yusupov, a nobleman and participant in the murder of Rasputin.[1][2] The script was approved by Yusupov and he also agreed to appear in the film.[1] In the introductory interview of the film, Yusupov demonstrated that his loathing for Rasputin remained undiminished.[3] Filming began at the Billancourt Studios in Paris in December 1966.[3] The film opened the 1967 Cannes Film Festival[3] and later that year was released theatrically in France on 3 May.
