My favorite film at Whitehead festival. Available at Netflix and Film Movement.

It is like Roshomon in that it tells the story over and over, but not as rigidly structured in that it's not just one person's perspective in each telling, rather it is taking a different route in following various people. (If you saw the play Tamara where you physically follow characters through a villa and can change who you follow at various points, it's a bit like that.)

Opening shot is one long take (my guess is about 2 minutes, but I didn't time it) that leads up to the point that becomes the touchstone that various iterations start at. The story of a group of soldiers who commit a crime and the cover up that follows. At risk is a witness to the crime that must be dealt with. But we also learn that they have all be witnesses to crime (i.e., the war). The ending may be just a touch over the top sentimentally, but other than that, a great and powerful film.

Won the Ecumenical jury prize and the Peace prize at Berlin.

Apparently the film Vantage Point also uses a Rashomon style narrative but this film seems to be in better taste. It's not new to be remaking Rashomon, it's been done many times as The Outrage, a 1961 television version by Sidney Lumet also called Rashomon, Iron Maze, Misty and even Hoodwinked! is a Rashomon rehash in a way.

I mention Roshomon to give an idea of the structure, which indeed has been used in various other films.

I'm actually reluctant to call Hoodwinked! a Rashomon-type story because the POINT of Rashomon was that none of the stories matched, whereas the point of Hoodwinked! is that the stories DO match if you take the time to put them together.

Do the stories in Witnesses match?

In Witnesses, there is just one story - you get more info with each iteration. But it allows you to see various points as it would seem to different characters. An example is a police detective at a funeral. The perps see his presence as a threat. Is he there working, or for some other reason? The reasons people react in various situations is because of what they know of the story, and at times, you know it as they know it, but other times you know differently. So in a sense it is somewhere between Roshomon and Hoodwinked. (In terms of quality, it is much closer to the former than the latter.)
