Victor, a disillusioned sexagenarian, sees his life turned upside down on the day when Antoine, a brilliant entrepreneur, offers him a new kind of attraction: mixing theatrical artifices and historical reconstruction, this company offers his clients a chance to dive back into the era of their choice. Victor then chose to relive the most memorable week of his life: the one where, 40 years earlier, he met the great love. The La Belle Epoque soundtrack features the film's original music composed by director Nicolas Bedos (Mr & Mrs Adelman) and Anne-Sophie Versnaeyen (I Still Hide to Smoke, Chambord). It also includes songs by Billie Holiday, Baccara, Player, and many more musicians. The movie's music perfectly fits the story and creates the mood to listen to it for hours.

In the first week of release, a record-breaking 550.000 people watched the movie in cinemas around France.

La Belle Epoque is available as a limited edition of 500 numbered copies on transparent blue vinyl.
