1.) You could get your hands on a video camera and film your own adventure. Which many fans did. And actually did very well. Or...
2.) Read the continuing adventures of the Doctor in a series titled New Adventures being published by Virgin Books and later BBC Books.
Which many of us young fans did. The Doctor, in his Seventh incarnation as portrayed by Sylvester McCoy, continued his adventures throughout time and space in a ship which had been stuck in the shape of a 1960's London police box since the series began in 1963. These adventures had the luxury (for the most part) of not being restricted by the budget and censorship which the television endured. And the writers could tell stories that were a tad more mature than what was had been seen on the BBC and readers began to see a much darker and Machiavellian version of the Seventh Doctor. Which was a direction the character seemed to be heading in before the series ended.
There were many writers who had written episodes for the television series had written stories for these "New" Adventures. Many of the young writers of that series such as Russell T. Davies, Gareth Roberts, Steven Moffat and Mark Gatiss would go on to write episodes for the series. And in the case of Davies and Moffat would go onto be the series showrunners and call the shots.
One of these young and budding writers was Paul Cornell. Who would become a fan favorite in the run of Doctor Who "New" Adventures and much like the writers mentioned above would go on to write for the current television series. Even one of his novels from the New Adventures "Human Nature" would be adapted into an episode. However, one of his earliest novels after Timewyrm: Revelation was "Love And War". Which would introduce a new companion for the Doctor in the series named Bernice Surprise Summerfield. Bernice, or Benny as her friends would call her, would go on to star in her own series of novels as well as a series of audio plays. These plays actually were what gave Big Finish Productions the final go ahead from the BBC to do a series of Doctor Who audio adventures in 1999.
Since then, not only has Paul gone onto write some memorable episodes for the current Doctor Who, but he has also gone on to write for comics. In particular for Young Avengers and Action Comics.
Most recently to commemorate the 20th Anniversary of the first appearance of Benny Summerfield, Big Finish has adapted Paul's novel Love and War into an audio play. Unlike his story Human Nature, this adaptation actually features the Doctor it was intended for with Sylvester McCoy providing the voice for the Seventh Doctor.
Reading many of the Doctor Who novels, I always felt the best stories I've felt are the ones that make me think "That would have made a smashing television episode". Although, this has not been adapted into a television episode, Jacqueline Rayner has done a smashing job adapting Paul's book into an audio.
Listening to it, this story would have made an excellent television episode for Sylvester McCoy's Doctor if the series were to have continued into a 27th Season. I've always felt both Colin Baker and Sylvester McCoy were sorely underrated during their respective times in the roles. Colin got sacked by the BBC and Sylvester got the series yanked out from under them.
Big Finish has done a great job in presenting this story. In this modern age we live in, audio is a difficult medium for people to get into. We have become very visual society. Especially in the United States where we really don't have much in terms of radio dramas the way they still do in in the UK.
Which is kind of sad. There is something warm and comfortable about sitting back and imagining what characters and scenes might look like.
Big Finish had already dabbled in the waters of the Virgin New Adventures with two previous Seventh Doctor and Benny audio dramas. One of which, Shadow of the Scourge, was written by Paul Cornell back in 2000.
However, it has left me wanting more. I would love to hear more adventures between the Seventh Doctor and Benny. Either adaptations from other stories or new tales. I think it's an avenue that needs to be explored more.
I highly recommend you go on Big Finish's website and order a copy or if you live in Worcester Massachusetts, stop on by Annie's Book Stop of Worcester and pick one up. You'll be glad you did!!
