I’m trying to remember this low-budget dystopian sci-fi film from the 2010s. The story follows young people who are forced into combat situations without understanding the real reason behind it all. The main protagonist is a young white male who develops romantic feelings for a female competitor during the battles. I believe the actress might have been Jamie Chung or possibly another Asian performer. The big reveal involves the contestants actually being elderly wealthy individuals who have somehow taken over younger bodies. The winner gets to permanently keep their youthful form as the ultimate prize. Does anyone know what movie this could be?
