The List of the Lord of the Rings film trilogy characters and cast members is a list of characters and cast members who appeared and voiced or portrayed characters appearing in the extended version of Peter Jackson's the Lord of the Rings film trilogy. Before filming began on 11 October 1999, the principal actors trained for six weeks in sword fighting (with Bob Anderson), riding and boating. Jackson hoped such activities would allow the cast to bond so chemistry would be evident on screen as well as getting them used to life in Wellington . They were also trained to pronounce Tolkien's verses properly. After the shoot, the nine cast members playing the Fellowship got a tattoo, the Elvish symbol for the number nine, with the exception of John Rhys-Davies, whose stunt double got the tattoo instead. The film is noted for having an ensemble cast.
