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

P.R.O.B.E. was a series of four videos produced by BBV Productions and made on a semi-professional basis. They featured Caroline John as Elizabeth Shaw, working for the Preternatural Research Bureau. Many former Doctor Who actors, including Doctors Jon Pertwee, Peter Davison, Colin Baker and Sylvester McCoy appeared in the series, playing different roles. Due to licensing restrictions, no explicit reference to The Doctor was allowed. Doctor Who alumni Louise Jameson co-starred with John in all four films, as Patricia Haggard.
