Hulke was involved with the socialist
Unity Theatre in the 1950s and 1960s, serving as its production manager in the mid-1950s, and wrote a booklet in 1961 celebrating the theatre's 25th anniversary. Hulke met writer Eric Paice at Unity and the two wrote as a team for television, beginning in the late 1950s with "This Day in Fear", which was produced by
BBC Television in 1958 as part of its
Television Playwright anthology series. In addition to the
Pathfinders series,
Crossroads, football soap
United!, ''
Gideon's Way, and was script editor for Spyder's Web''. His scripts for
Doctor Who were known for avoiding black-and-white characterisation and simplistic plotting. Military figures are usually presented unfavourably –
Invasion of the Dinosaurs and
The Ambassadors of Death both have a general as the ultimate villain. One of his best-known contributions to the series is
Doctor Who and the Silurians. This story depicts an encounter between the human race and the remnants of a technological reptilian race that ruled Earth in prehistoric times. Hulke avoids casting either side as heroes or monsters. He was a friend and mentor to
Terrance Dicks, with whom he collaborated in 1962 on
The Avengers episodes "The Mauritius Penny", (which was Dicks' first television credit), "Intercrime", "Concerto" and "Homicide and Old Lace";
The War Games, Dicks' first
Doctor Who script, and on the non-fiction book
The Making of Doctor Who. He also contributed to
Target Books' range of
Doctor Who novelisations, adapting many of his scripts before his death, as well as 1973's
The Green Death. Hulke's novelisations were noted for providing a wealth of additional background detail and character depth. He wrote an influential screenwriting manual,
Writing for television in the 70s in 1974, and an updated version,
Writing for Television, which was released posthumously in 1981. ==Death==
