According to this story, there’s to be a new character in The Return of the King when it comes out in December. It’s Jar-Jaromir, half brother of Boromir and Faramir. According to the story:
The scene depicted in the trailer shows Jar-Jaromir shouting, “Gondora gonna fallsa”; he then trips over a corpse and knocks down a couple of Uruk-hai.
My favorite quote from the article is this:
[Peter] Jackson added, “I just love it when he shouts, ‘Yousa steala precious from meesa!'”
