List of submissions for Best International Film 2023.

And we already started. The competition for the Oscar for Best International Film begins and we will see each participating country selecting the film that will represent them. To participate, the film needs to be released in theaters between January 1, 2022 and November 30, 2022.

Switzerland

Switzerland has chosen as its representative for the Oscars A Piece of Sky (Drii Winter) which is about Marco and Anna who try to live a life in a community in the Alps until the disease arrives. The film received a Special Award at the Berlin Film Festival.
Switzerland has been nominated for an Oscar five times, of which it has won twice with Dangerous Moves (1985) and Journey of Hope (1991).

Yes, exactly. My Life as a Courgette represented Switzerland at the Oscars and was not nominated, although it was on the shortlist. But if it was nominated for an Oscar for Best Animated Film.
It is not one of the five Swiss films that have been nominated for an Oscar for Best Foreign Language Film/Best International Film but it is a curious case.
Another similar case occurred when France selected Persepolis in 2008 but it was not nominated but was nominated for Best Animated Film. 

Crazy that this is the first time they're picking Park.

Not really surprising. Korea is extremely prudish and homophobic. They would never pick something super out there like The Handmaiden or Oldboy.

Uruguay

Uruguay on this occasion becomes the first Latin American country to select its representative film for the next Oscars. El empleado y el patrón (The Employer and the Employee) and the film is about two men, one an employee the other a boss, who are pressured to make money and support their families. Then the tragedy occurs.
The film is starring by Cesar Winner Nahuel Pérez Biscayart (120 battements per minute)
Uruguay has an interesting trivia in this category. In 1992 A Place in the World directed by Adolfo Aristarain was not chosen to represent Argentina at the Oscars. So the director convinced the Cinematheque of Uruguay to have his film represent Uruguay. The film was nominated for an Oscar but a complaint alerted the Academy that the Uruguayan film was actually Argentine, which caused the disqualification of the film although it was not replaced (leaving only four nominated films)
Officially Uruguay has never been nominated for an Oscar.

Germany

The German representative for the next Oscars has been chosen and it is All Quiet on the Western Front adaptation of the novel of the same name written by Erich Maria Remarque and that deals with the experience of a young soldier whose enthusiasm disappears when he faces the horrors of World War I.
The film stars the great Daniel Brühl. And it was already made into a movie in 1930 with the version that won 2 Oscars including Best Picture.
Germany is one of the most successful countries in the category of Best International Film with 19 nominations (counting the nominations since the unification of the two Germany and the nominations received by West Germany) and has won three Oscars: The Tin Drum (1980) Nowhere in Africa (2003) and The Lives of Others (2007)
