In 2009, Courtney reprised the role for a final time in the short film "Liberty Hall", an extra for "Mawdryn Undead"s DVD release. The film is a seven-minute mockumentary where a fictional journalist interviews the Brigadier about his life. The Brigadier discusses his marriages with Fiona and Doris, and mentions his daughter Kate and grandson Gordon (referencing "Downtime"). He states that his most recent encounter with the Doctor took place in 2000, when he was on unofficial UNIT business in Malebolgia in the United States (referencing the Eighth Doctor audio drama "Minuet in Hell"). He concludes, "So, now I've hung up my uniform for good... unless I hear that a blue police box has been found somewhere, and then, don't you worry, I'll be ready!"
