Info on ROTK Movie (MAJOR SPOILERS)
Okay, I've learned some information on events that take place in the third film, and these are all very reliable. The bit about Saruman is 100% true. I've seen production photos of him impaled on the spikey wheel. Also, it would appear that the scouring of the shire may not take place. Because Saruman dies in fact at Orthanc. This is courtesy of theonering.net
"I have a friend who told me about Return of the King, first thing, Sauron will be standing off against Aragorn in hand to hand combat
Men of Gondor surround them both and Legolas shouts "Aragorn!" as a warning, then Aragorn with Anduril in hand rushes the Dark Lord who looked like he was in different armor than when we saw him in the prologue. It is not an even fight and Aragorn is nearly knocked to death as the countdown to the destruction of the ring begins. I guess the goal is to make the audience wonder if the ring will be destroyed before Aragorn is smeared all over Mordor!
Another thing I saw was the death of Saruman. Grima slits Saruman's throat and kicks him over the edge of Orthanc where he is impaled on the wheel, then Legolas shoots an arrow high into the air and is laughed at by Grima as it soars over his head, as Grima is mocking the seemingly inaccurate Legolas the arrow comes spiraling down straight through Grima's skull!"
