Mark's original TV series TELL ME EVERYTHING was commissioned for a second season after the first launched on ITVX to great reception. The show is produced by Noho Film & TV for ITVX. Series two will drop on ITVX in 2024.

Mark has recently made a documentary-sitcom about his experience of sexual abuse, which will soon air on Channel 4. He is now developing a new original series with The Forge and he's working with Larry Dean on a project for Big Talk. Mark is the co-creator, writer, executive producer and director of LEE AND DEAN, and plays Dean in the series. LEE AND DEAN was produced by Mark’s and Miles Chapman’s indie Bingo Productions for Channel 4. 

Previously, Mark directed and produced a non-TX taster called HITMEN, starring Ricky Grover through Bingo Productions for Channel 4. He directed a promo for Ken Loach's film I, DANIEL BLAKE which was produced by Entertainment One / Don’t Panic and ACCESS ALL AREAS, a short starring Jason Watkins for Guide Dogs / Don’t Panic.

As a writer, Mark contributed with material to MORGANA ROBINSON'S THE AGENCY for Happy Tramp / BBC Two and THE NIGHT BEFORE CHRISTMAS for Arts Assembly. He has developed an original series, I DO TOO, with Steve Thompson for ITV. As playwright, Mark wrote FOUR WALLS for The Bush Theatre.

Mark is also an actor and a performer. Mark played the role of DEAN in his much-loved series and he also stars in TELL ME EVERYTHING, HBO’s THE NEVERS and the BBC’s THE JAVONE PRINCE SHOW.
