Arthur and Mordred scene (spoilers)

I can think of 2 films that have played a riff on the scene where 2 kill each other. Star Trek: Nemesis although it is just Shizon who is killed the scene plays out almost exactly, it is also interesting to both Patrick Stewart and the costume designer Bob Ringwood worked on both films. BvS:DoJ has Superman and Doomsday killing each other just like Arthur and Mordred and also the cinema the Wayne family come out of is showing Excalibur.
