A British touring production of “To Kill a Mockingbird,” which was to start next month, has been canceled after Scott Rudin’s company Atticus — the firm behind the Broadway hit — threatened legal action.

The British production was to use the playwright Christopher Sergel’s adaptation of Harper Lee’s book, a version that has long been popular in schools.

Jonathan Church Productions, the Curve Theater in Leicester and London’s Regent’s Park Theater said in a statement that they had obtained a license for the production from Dramatic Publishing, an Illinois-based company that licenses Mr. Sergel’s adaptation.

But on Jan. 11, Atticus’ lawyers threatened action if the tour was not canceled, saying it held worldwide rights for professional stagings of the book. The team at Atticus was “unwilling to consider any compromises which were proposed to resolve the situation without lengthy and costly legal action,” the statement added.
