In Nemesis, Shinzon dies when he attacks Picard with a knife, and Picard pulls loose a strut or some other object and impales Shinzon. Shinzon forces himself down the shaft of the "spear", and grasps at Picard's throat with his last breath. Picard-Shinzon showdown at 2:17 mark.
In the 1981 King Arthur film Excalibur, Mordred impales his father with a spear. Arthur, mortally wounded, claws his way down the spear, to drive Excalibur into Mordred's chest, slaying him. Arthur slays Mordred.
Though not identical, the two scenes have many similarities. I've long wondered if there was an intentional nod to the earlier film. Is there any official information to confirm this?
