What's up with The Lord of the Rings: The Two Towers? Though the Rings sequel wrapped filming last year, director Peter Jackson has called several cast members — including Ian McKellen, Viggo Mortensen, Elijah Wood and Liv Tyler — back to New Zealand to shoot new scenes, FoxNews.com reports. While New Line Cinema insists it's only adding small stuff, it's speculated that Jackson wants to spice up Tyler's onscreen romance with Mortensen.
