LONDON — The Venice Film Festival has added Patrice Leconte’s “Une Promesse,” which stars Rebecca Hall, Alan Rickman and Richard Madden, to its lineup as an out-of-competition screening. The fest also named four other titles to complete the program of the 70th edition.

In addition, the fest tapped actress, scriptwriter and author Carrie Fisher as the final member of the international jury of the Venezia 70 Competition, while Mexican director Amat Escalante will complete the international jury for the Luigi De Laurentiis Venice Award for a debut film.

Finally, “Venezia 70 — Future Reloaded,” which is composed of short films made by 70 helmers to celebrate the fest’s 70th anni, will be the second opening film at the opening ceremony. It will be screened on Aug. 28 following Alfonso Cuaron’s “Gravity.”

“Une Promesse,” which makes its world preem at the fest, was penned by Leconte and Jerome Tonnerre, adapted from the novel by Stefan Zweig. It takes place in Germany in the period preceding World War I, and centers on a woman who falls in love with the young assistant to her husband, a rich and powerful industrialist.

Leconte’s pics include “Monsieur Hire,” “The Hairdresser’s Husband,” “Ridicule,” which received an Oscar nom, “The Man on the Train” and “Intimate Strangers.”

Three docus have been added to the program: Gabe Klinger’s “Double Play: James Benning and Richard Linklater” (Venezia Classici — Film History Documentaries); Marco Spagnoli’s “Donne nel mito: Anna Magnani” (Venezia Classici — Film History Documentaries); and “Dai nostri inviati — La Rai racconta la Mostra del Cinema 1980-1989,” helmed by Enrico Salvatori, Giuseppe Giannotti and Davide Savelli (Out of Competition — Special Events).

Finally, “Dietro le quinte di 8 e ½,” in which Gideon Bachmann presents live his collection of 170 snapshots taken during the making of Fellini’s masterpiece, plays as part of the Special Events section, completing the one-day tribute to Fellini on Sept. 6, which will feature the world premiere of Ettore Scola’s “Che strano chiamarsi Federico.”

The festival runs Aug. 28 to Sept. 7.
