John Le Carré spy drama is moving closer towards a second series after signing up-and-coming British writer Matthew Orton to pen The Ink Factory-produced series.

Orton, who has penned a number of feature films for MGM and Fox, is presumably writing new episodes of the BBC and AMC co-production. It comes after The Ink Factory co-founder Simon Cornwell, son of Le Carré author David Cornwell, said earlier in 2017 that the producers were keen to tackle a sequel. “There’s no book and there’s never been a Le Carré story that has been extended beyond the confines of the novel. It would be interesting to try that,” he told an audience at the Royal Television Society.

The Night Manager director Susanne Bier also said in March that a follow-up was “slowly being developed” but that the creators were taking their time to make sure series two “lives up” to the first series. The finale of the first series, which was written by David Farr, secured more than nine million viewers on the BBC when it aired in March 2016.

The first series featured Tom Hiddleston as enigmatic Jonathan Pine, who goes undercover to expose billionaire arms dealer Richard Roper, played by Hugh Laurie. Hiddleston also said he would consider appearing in a second series.
