Following a series of meetings with each film's producers and sales agents, the committee chose Memoir of War by Emmanuel Finkiel to join the 90 other candidates in this category that have so far been announced by their respective countries (the closing date for submissions is October 1).

The five remaining films that will compete for the Oscar will be announced along with all other nominations on January 22, 2019, prior to the 91st Academy Awards ceremony, which will be held on February 24 at the Dolby Theater in Hollywood.
