Munro wrote the last serial of the original Doctor Who in 1989, and returned to the show in 2017, writing an episode for the tenth series of the revived version. This made her the only writer thus far who has worked in both the classic and revival eras of Doctor Who.[2]
Her history cycle The James Plays, James I, James II, and James III, were first performed by the National Theatre of Scotland in summer 2014 in a co-production with Edinburgh International Festival and the National Theatre UK. The plays were staged again in early 2016. She followed this up with James IV - The Queen of the Fight in 2022. Her other credits include the theatre play Iron which has received many productions worldwide. Other theatre works include plays for the Traverse Theatre Edinburgh (Fugue, Your Turn To Clean The Stair, Strawberries in January translation), Manchester Royal Exchange (Mary Barton, Scuttlers), Plymouth Drum Theatre and Paines Plough (Long Time Dead), and the Royal Shakespeare Company (The Indian Boy, The Astronaut's Chair).
In 2006 the Lyric Theatre, Hammersmith presented Munro's adaptation of Richard Adams' classic book Watership Down. Her early television work includes episodes of the drama series Casualty (BBC) and, more recently, a BBC film, Rehab, directed by Antonia Bird.
