Soon after leaving as script editor on Doctor Who, he and Terry Nation served as the principle writers of the ITC action adventure series The Baron. Spooner spent the majority of the next five years at ITC, for which he co-created Man in a Suitcase. Along with Monty Berman, he helped create various successful series for ITC, such as The Champions, Department S, Randall and Hopkirk (Deceased) and Jason King. He served as script consultant on all four, but only wrote for the latter. During this time he wrote an episode of The Avengers, having previously written two scripts for it in 1961.
In the 70s and 80s, Spooner wrote scripts for Doomwatch, Paul Temple and Bergerac for the BBC, UFO and The Protectors for ITC, Thriller for ATV and The Professionals for LWT. Spooner died of a heart attack in 1986.
