The book was partially adapted for film in 2007 as The Golden Compass, although the movie was not successful and the second and third novels (The Subtle Knife and The Amber Spyglass) were not adapted. This time around, the BBC and HBO plan to adapt all three books. Season 2 has already been greenlit and is in pre-production. Early reports suggested that they were looking to adapt the trilogy across five seasons, but the new trailer suggests that the first season may adapt the entirety of the first novel instead.
Season 1 is set to be released in the autumn, with some reports suggesting it may debut around the time that Pullman's next novel in this universe, The Secret Commonwealth, is published (on 3 October). HBO will air the series in the United States.
