If it was possible to cut someone out of the movie, who would it be?

I don't think you could cut out Rosie Cotton. Tolkien liked to tie up lose ends, so we really need Sam to marry so his children can pass the Red Book down. I think there will be something about the Red Book in ROTK, so Rosie is needed.
Arwen needs to be in so Aragorn can marry her and thus Gondor will have a king for many years to come. Every hates Arwen because she turned 'Xena' in the FOTR. If the film's writers changed her role I'm sure we would like her much more.
Definitely Lurtz could be cut out, and perhaps Hama as well. What about Legolas? The only thing he suceeds in doing is bringing crazed fan girls to movie forums...
