Elsa Keslassy International Correspondent Maïwenn’s historical drama, “Jeanne du Barry,” starring Johnny Depp as Louis XV, is slated to world premiere on opening night of the 76th edition of the Cannes Film Festival, Variety has learned. The movie marks Depp’s acting comeback after a three-year hiatus following his long legal battle with ex-wife Amber Heard which culminated in a defamation trial won by Depp in December. Maïwenn’s sixth feature, the period movie revolves around the tumultuous relationship of the French king Louis XV and his lover, Jeanne du Barry (played by Maiwenn), whom he brought into the Versailles Palace to live near him even though she wasn’t a noble. Louis XV, who was nicknamed “the beloved,” ultimately died as an unpopular king after being accused of corruption. He reigned for 59 years, the longest in the history of France after that of Louis XIV. Depp barely spoke French before the start of filming so it will be interesting to see how he pulls it off without an accent.
