A series producer is a senior member of the production team, but one that has been rarely credited in the history of DWU productions.
Matthew Bouch was the series producer credited throughout series 2 of The Sarah Jane Adventures (2008). He had served as producer in the previous series, on all stories apart from Invasion of the Bane.
Marcus Wilson was a series producer credited during series 7 of Doctor Who (2012-13), as well as on Closing Time during series 6. His first producer credit was on The Impossible Astronaut, at the start of series 6 in 2011.
