Ringer Spy Ciggy Fagash was involved in an interview with Miranda Otto and writes:

“I know Lawrence Makoare and Sala Baker are both supposed to have been doing work as the Witch King in the final battle with Eowyn – and she mentioned they’d be reshooting a lot of it, so that could explain at least some of Baker’s work [Sala’s presence at reshoots have been mentioned in recent news – T] “She also mentioned not holding out too much hope that much of the Houses Of The Healing would appear. Apparently the romance between Eowyn and Faramir, although definitely present, has been down-played somewhat. She seemed disappointed but said, ‘well something has to make way – there’s a lot of story to cover in the last film.'”
