List of Doctor Who: The Classic Series audio plays by Big Finish

The dramas feature both former actors who portrayed the Doctor and his companions, and new continuing characters as well as elements from other spin-off media. The canonicity of the audio dramas, as with other Doctor Who spin-off media, is unclear. To date, productions have featured the Fourth (Tom Baker), Fifth (Peter Davison), Sixth (Colin Baker), Seventh (Sylvester McCoy) and Eighth (Paul McGann) Doctors portrayed by their original actors. Big Finish's current licence from the BBC allows it to produce audio dramas featuring the first thirteen incarnations of the Doctor and associated characters introduced into the series between 1963 and 2022. Nearly all of the companions from the original series have appeared, voiced by their original actors. They include Susan (Carole Ann Ford), Ian Chesterton (William Russell), Vicki (Maureen O'Brien), Steven Taylor (Peter Purves), Sara Kingdom (Jean Marsh), Polly (Anneke Wills), Jamie McCrimmon (Frazer Hines), Victoria Waterfield (Deborah Watling), Zoe Heriot (Wendy Padbury), Jo Grant (Katy Manning), Brigadier Lethbridge-Stewart (Nicholas Courtney), Sergeant Benton (John Levene), Mike Yates (Richard Franklin), Leela (Louise Jameson), K9 (John Leeson), Romana I (Mary Tamm), Romana II (Lalla Ward), Adric (Matthew Waterhouse), Nyssa (Sarah Sutton), Tegan Jovanka (Janet Fielding), Vislor Turlough (Mark Strickson), Peri Brown (Nicola Bryant), Melanie Bush (Bonnie Langford) and Ace (Sophie Aldred). Several actors who played the Doctor and companions of previous Doctors have appeared in other roles, including Russell, O'Brien, Marsh, Wills, Watling, Padbury, Caroline John, Manning, Elisabeth Sladen, Leeson, Daphne Ashbrook, Tennant and Bernard Cribbins. Sladen also reprised Sarah Jane Smith in a spin-off series simply entitled Sarah Jane Smith. Sladen never appeared as Sarah alongside any incarnation of the Doctor for Big Finish; a series with Tom Baker was planned, but was never recorded due to Sladen's untimely death in April 2011. Initially Matthew Waterhouse declined to reprise the role of Adric so the character was recast and played by Andrew Sachs as an older version of the character. Waterhouse later returned to the role on an ongoing basis. Big Finish also started The Companion Chronicles series of plays, featuring a companion or friend of the Doctor and a supporting cast member. Ford, Russell, O'Brien, Purves, Marsh, Wills, Hines, Watling, Padbury, Manning, Jameson, Tamm, Ward, Sutton, Strickson and Aldred have all reprised their roles in this series along with John (Liz). As well as this, Big Finish started the Doctor Who: The Early Adventures series of full-cast plays, featuring the First Doctor (recast to William Russell and Peter Purves, following William Hartnell's death in 1975) and the Second Doctor (recast to Frazer Hines, following Patrick Troughton's death in 1987), and companions Barbara Wright (recast to Maureen O'Brien and Jemma Powell, following Jacqueline Hill's death in 1993) and Ben Jackson (recast to Elliot Chapman, following Michael Craze's death in 1998), and Russell, Ford, O'Brien, Purves, Marsh, Wills, Hines, Watling and Padbury reprising their roles from the original series. They also started The Third Doctor Adventures series of full-cast plays, featuring Tim Treloar recast as the Third Doctor (following Jon Pertwee's death in 1996), Manning as Jo, and Franklin as Yates. New companions created for the audio series include Evelyn Smythe (Maggie Stables), Charley Pollard (India Fisher), Erimem (Caroline Morris), Hex Schofield (Philip Olivier), C'rizz (Conrad Westmaas), Lucie Miller (Sheridan Smith), Thomas Brewster (John Pickard), Abby (Ciara Janson), Tamsin Drew (Niky Wardley), Elizabeth Elizabeth Klein (Tracey Childs), Flip Jackson (Lisa Greenwood), Molly O'Sullivan (Ruth Bradley), Liv Chenka (Nicola Walker), Helen Sinclair (Hattie Morahan) and Constance Clarke (Miranda Raison). Lisa Bowerman has appeared as Bernice Summerfield, a companion from the Virgin New Adventures, in several Doctor Who audio dramas as well as in original productions with her as the central character. Robert Jezek and Jemima Rooper have appeared as Frobisher and Izzy Sinclair, companions from the Doctor Who Magazine comic strip, Travis Oliver and Yasmin Bannerman have portrayed companions Roz Forrester and Chris Cwej from the Virgin New Adventures, and Matt Di Angelo has played Fitz Kreiner, a companion from the BBC Eighth Doctor Adventures. Charley, C'rizz, Lucie, Tamsin and Molly were all referenced by name in the mini-episode "The Night of the Doctor". ==Broadcast==
