The new poster is similar to the first one, with the two towers of Barad-dur and Orthanc on it, but it also shows some images of the cast.
Most of them are pretty recognisable because they were in the first film, but the poster also shows new characters Eowyn and Gollum.
The Lord of the Rings: The Towers is the second film in the trilogy, and is released on 18 December.
And with the world premiere of Harry Potter and the Chamber of Secrets this weekend, the battle for the box office is heating up.
