In an interview with the Guardian, writer Steven Moffat had this to say when asked if Sherlock will ever return to television:
“I would be astonished if it didn’t come back. We all think it would be quite nice to rejoin them once a few years have gone by. Normally Sherlock Holmes and Dr Watson are portrayed in their 50s and we did them in their 30s. I’m not saying we’re going to wait 20 years but it would be quite nice to leave it a while.”
Moffat spoke to the Guardian to promote his very first play produced, The Unfriend, which he has written. The play is directed by his Sherlock co-creator Mark Gatiss.
The Unfriend will be part of Chichester Festival theatre’s 2020 season and will star Amanda Abbington, Reece Shearsmith and Frances Barber.
