* ActingForTwo: You'd be hard pressed to find a Big Finish story, that didn't have at least one actor playing multiple parts.
* ProductionPosse: A great number of actors, writers and directors have regularly contributed to several Big Finish productions, despite many of them not being permanent members of the company. Acting wise, two of the most prolific mainstays are Creator/LisaBowerman, and the late Creator/DavidWarner.
* SharedUniverse:
** The majority of their audio series take place in the Franchise/{{Whoniverse}}, being that they are all ''Series/DoctorWho'' spin-offs, with some unrelated series have a few references to ''Doctor Who''.
** Creator/BigFinish created a loosely connected shared world for their ''Literature/SherlockHolmes'', ''Series/DarkShadows'' and ''AudioPlay/TheConfessionsOfDorianGray'' series. The ''Confessions'' series is what mainly connects the three through crossovers and CharacterOverlap, as Holmes appears in "Ghosts of Christmas Past" and voiced by his Big Finish actor Creator/NicholasBriggs, and ''Confessions'' has numerous references to ''Dark Shadows'', with Dorian Gray himself appearing in "The Darkest Shadow" and voiced by his ''Confessions'' actor Creator/AlexanderVlahos.
* WhatCouldHaveBeen:
** There was nearly a range based off of the cult American sci-fi show ''Series/{{Firefly}}'', which never happened either due to money or rights.
** Had Creator/JohnHurt not passed away, he was very much prepared to more stories with Big Finish beyond his signature role as the War Doctor. Playing the title character in ''Literature/TheInvisibleMan'' gave us taste of what it could've been.
