In our report of the litigation between the Tolkien family and New Line Cinema, producers of The Lord of the Rings (May 25), we did not make it clear that Christopher Tolkien is suing as a trustee of the Tolkien Trust, a registered charity, and the JRR Tolkien 1967 Discretionary Settlement. It was another member of the family who referred to the action as “one last crusade”, not Mr Tolkien, and the hearing on June 6 was to fix a date for the eventual trial, not actually to halt Hollywood plans to film The Hobbit. We apologise to the trustees and Mr Tolkien for these errors.
