I watched
Tombstone Rashomon on Amazon Prime last night, and really enjoyed it. This was completely off of the beaten path. The concept is that a modern-day film crew heads to Tombstone to film the gunfight at the OK Corral, but they arrive a day late. So instead they interview all of the participants and witnesses.
It really is worth a watch. It has creative moments, while lending a new perspective to the historic event. The interview with Big Nose Kate was confusing due to her use of pronouns, but I won't ruin any of it. Just watch for yourself.
Don't forget the popcorn.
