Stephen Gallagher

Stephen Gallagher (born 1954) is an English writer.

He has written several novels and television scripts, including for the BBC television series Doctor Who – for which he wrote two serials, Warriors' Gate (1981) and Terminus (1983) – as well as for the series Rosemary & Thyme and Bugs, for two seasons of which he was script consultant along with Brian Clemens. He adapted his own novel Chimera for ITV and directed the adaptation of Oktober as well as writing the feature-length episode The Kingdom of Bones for the BBC series Murder Rooms.

He also developed and wrote a science-based series for ITV, Eleventh Hour, starring Patrick Stewart as a government science investigator and advisor. The program was rumoured to be ITV's answer to the new series of Doctor Who, but was more in the tradition of the hard-science thriller. Gallagher's series format was acquired for a US television remake by the CSI trio of CBS, Jerry Bruckheimer TV and director Danny Cannon. The series aired on CBS and starred Rufus Sewell and Marley Shelton.
