Tehanu picked this up from PJ’s publicist:
With three event films being shot consecutively over more than a year in New Zealand, Lord of the Rings is an unprecedented production of size and scope. During the coming months, the producers will cast close to 100 roles of substance for this adventure trilogy. The search to complete this ensemble literally spans the globe. New Line Cinema recognizes the substantial media interest in this project and will assist journalists at the appropriate time. However, the studio will no longer comment on completed deals, current negotiations, rumors or speculation about any specific role. When casting of principals has concluded, New Line, along with the filmmakers, will unveil the entire ensemble and announce further newsworthy specifics about these tentpole films.
