Their Doctor Who plays are highly regarded. They use the actual TV actors to play the role of the cosmic hobo - Peter Davidson, Paul McGann, Sylvester McCoy and Tom Baker are among the previous TV doctors who have recorded for the company. Big Finish began with a series of audio plays adapted from New Adventures. These were a series of novels from Virgin Books which had originally been licensed Doctor Who stories, but by then had become officially independent from the show and were based around the character of Bernice "Benny" Summerfield. Big Finish then obtained a (non-exclusive) license to produce official Doctor Who plays, beginning with the multi-Doctor story The Sirens of Time. Doctor Who and spin-offs have remained the main part of the company's output ever since, although they have since diversified. Until July 2006, Gary Russell served as producer of the Doctor Who audios. When Russell left the company, Haigh-Ellery and Nicholas Briggs took joint responsibility as Executive Producers.
Though it's not all Doctor Who - the company have done plays based on Sapphire and Steele, The Tomorrow's People, various 2000AD characters, Stargate and many more.
Sherlock Holmes and The Ripper is based on a stage play by stalwart TV scriptwriter Brian Clemens. The writer of course is best known for his work on The Avengers, The Protectors, The Professionals and his work with Hammer Films. He is also a distant relation of Mark Twain.
It's an atmospheric tale with an audacious showdown in the PM's office.
