- You may be looking for a list of televised cliffhangers, a list of comic cliffhangers or a list of audio cliffhangers.
A cliffhanger is a standard device of serial fiction. It involves the heightening of dramatic tension at the end of an episode to such a degree that the viewer is made anxious about the fates of the protagonists. This, the producers of the work hope, will inspire viewers to return for the next episode, so that they can see how - or if - the protagonists survived.
Cliffhangers were included at the end of almost every episode of the 1963 version of Doctor Who. Most typically, the only episode free of cliffhangers was the last one in a serial, although there were periods - such as most of the 1960s and season 19 - where even these episodes had at least mild cliffhangers.
The device is still used in the BBC Wales version of the show for multi-episode storylines. A cliffhanger has also been a feature of the last episode of the first three series, in which it served to point to that year's Christmas special.
Cliffhangers are less prominent parts of earlier Torchwood narratives, although each episode of Children of Earth and Miracle Day used them. Conversely, The Sarah Jane Adventures regularly employs cliffhangers, in a style that directly echoes so-called "classic" Doctor Who. SJA stories universally have cliffhangers between parts one and two. Series-ending cliffhangers are much less common in the spin-off series. Only the Torchwood series 1 finale ends in a cliffhanger that is directly resolved in a later episode. Unusually, this cliffhanger resolves in both Utopia and Kiss Kiss, Bang Bang, and it is not strictly necessary to have seen Utopia to understand its Torchwood resolution. Series 4 ends on a cliffhanger that unusually didn't get resolved on TV, but rather continued in audio form.
P.R.O.B.E. had two cliff-hangers; the reveal of Patient One in The Zero Imperative and Christian Purcell's disappearance in The Devil of Winterborne. Whilst the second cliff-hanger is resolved in Ghosts of Winterborne, Patient One is never revisited.
A cliffhanger was part of the finale of the short-lived spin-off series Class, which has yet to be resolved due to the show's untimely cancellation.
As documentary subject
The quality of various cliffhangers - in terms of their efficacy to make viewers return the next week - was the subject of a short documentary, Now, Get Out of That, on the Terror of the Vervoids DVD.
In 2015, the Twelfth Doctor sat at an American diner ordering drinks while telling a story of a gang boss and his men. Because the Doctor kept interrupting himself in the middle of it, Clara Oswald remarked that "[he] like[d] a cliffhanger". (TV: Hell Bent)
