Phoebe, who is the show’s creator, has said that Fleabag has ended its run, but she and Andrew are set to become co-stars again in season two of His Dark Materials.
Andrew is also well known for his role as Moriarty in Sherlock, alongside Benedict Cumberbatch and Martin Freeman.
Later this year Andrew will star in Showtime’s adaptation Patricia Highsmith’s The Talented Mr Ripley, based on the story of the famous conman who manipulates his way to the top of London society.
Andrew recently said that despite doubts, he believes viewers can adapt to intellectual pieces of television in the era of binging and box sets.
