In November 2015, BBC One announced that it had commissioned a television adaptation of His Dark Materials, to be produced by Bad Wolf and New Line Cinema.[4] The eight-part adaptation had a planned premiere date in 2017, however in April 2017, writer Jack Thorne said to Radio Times that the series was still in pre-production. He said, "It’s at an exciting point where we’re just throwing things at the page and trying to work out what works and what doesn’t," and that he wanted to ensure that they were being loyal to the books.[5]
