P.R.O.B.E. (series)

P.R.O.B.E. was a series of direct-to-video films produced by BBV Productions, with four of its five instalments being released during the period of Doctor Who ' s cancellation.

The series starred Caroline John as Dr Liz Shaw and featured her adventures working at the Preternatural Research Bureau, investigating unusual phenomena whilst struggling with the indifference and derision of the government and the police.

Premise
The series followed Liz Shaw some years after she left UNIT and the Doctor. As established in The Zero Imperative, Liz was headhunted to set up a department for the Ministry of Defence called the Preternatural Research Bureau (or P.R.o.B.e.) because of her work at the University of Cambridge. She accepted but was unaware that P.R.o.B.e. was to be grossly underfunded, understaffed and based in a single cramped office at Ashley House.

Unlike UNIT, P.R.o.B.e. was a special division answerable to the British government with its purpose being to investigate the strange and the out of the ordinary. Liz's only colleague was assistant Louise Bayliss, who was transferred by minister Brian Rutherford in a bid to have the organisation closed. However, permission was required from Liz's ministry liaison and later lover Patsy Haggard, who refused to do so and frequently went out of her way to assist Liz.

Although mention of the Doctor and the events of season 7 was forbidden due to licensing restrictions, a number of Doctor Who actors featured in the series in new roles, notably Jon Pertwee, Peter Davison, Colin Baker and Sylvester McCoy and Louise Jameson in the recurring role of Patsy.

The first four films were written by Mark Gatiss and directed by Bill Baggs. After Caroline John's death in 2012, the role of Liz was recast and given to Hazel Burrows in When to Die, a tribute to John written and directed by Baggs. Jameson did not return as Patsy, who was instead played by Georgette Ellison.

Production team
