The movie won the Golden Palm award that year, which is the highest award at the Cannes Film Festival in Cannes, France. The movie was also a big hit with young people for its anti-establishment, wild feel. This was especially true because it was really seen to be about criticizing the Vietnam War that was going on at the time. That theme was only hidden somewhat by the setting of the movie during the earlier and less controversial Korean War.
