Matthew Graham wrote the 2006 (Series 2)Doctor Who episode Fear Her and the 2011-two-parter- The Rebel Flesh and The Almost People. - the fifth and six episodes of the sixth series. Graham is best known as the co-creator of the series Life on Mars (which starred John Simm) and its sequel series Ashes to Ashes. He has also noted that the main character of Life On Mars, Sam Tyler, was named after Rose Tyler (albeit accidentally, as Graham had trouble thinking of a surname and took his daughter's suggestion of Tyler without realising her reasoning for choosing it).
