(Simple) sequel

 The most common approach is for the events of the second work to directly follow the events of the first, either picking up dangling plot threads or introducing a new conflict to drive the events of a second story. A sequel to the first sequel might be referred to as a third installment or threequel or second sequel

 

Prequel

 

A sequel that portrays events which precede those of the original work is called a "prequel. These can often avoid the plot problems associated with having to deal with the consequences of the original (e.g. the death of an important character). However, they pose the challenge of maintaining dramatic interest when the outcome is already known from the original work, so the focus is usually on the character interactions or revealing how the characters and situations of the original work developed. Examples of prequels are Butch and Sundance: The Early Days, which is recognized as one of the first film prequels, and the Star Wars prequel trilogy.

 

Interquel

 When there are already two or more completed works, an interquel can portray events that happened between them, bridging one story to the other. The interquel is therefore a sequel to one work and a prequel to another. For example, the video game Kingdom Hearts 358/2 Days was released after Kingdom Hearts and Kingdom Hearts II, but takes place between them. Interquels are often ancillary works in other media rather than works in a popular series. For example, the novel The Godfather Returns takes place between the events of the films The Godfather and The Godfather Part II.


 

Midquel

 A midquel is a sequel which takes place during a chronology gap within a single previously completed work. For example, the Narnia book The Horse and His Boy takes place during the reign of the Pevensie children, which happens towards the end of The Lion, the Witch and the Wardrobe. Another example would be the film Bambi II, which starts out shortly after the death of the young deer's mother in Bambi but before the later scenes in which he is an adult.

 

Parallel

 In a parallel story, as with a prequel, the focus is not on the outcome but on the characters and previously unrevealed information. For example, Ender's Shadow covers the events of the previous novel Ender's Game from the point of view of a supporting character in the original.

Spin-off

 A variety of sequel that allows substantial creative freedom is one that is set in the same fictional universe as the original work, but with unrelated plots, and sometimes unrelated characters. When done with the intention of launching a new series of stories, these are often called spin-offs.One example of this is the The Cleveland Show, which is based on Family Guy. Screenwriter David Peoples described his film Soldier as a "sidequel" to Blade Runner, which he co-wrote

 

Spiritual successor

 A spiritual successor is a creative work that in terms of function and originator resembles a previous work, but officially is not titled a continuation.^[12] While a companion piece does not necessarily need to take place within the same "universe" as the predecessor, it must follow-up on specific themes and ideas introduced in the original work. It must also be intentionally meant by its creator to be viewed alongside or within the same context as the earlier work. An example is Letters from Iwo Jima, which is Clint Eastwood's companion piece to his earlier picture Flags of Our Fathers.

 

 

Reboot

 A reboot is a type of sequel which technically is not a sequel. It means that a franchise begins anew, as if the earlier entries in the franchise did not exist. Examples include the Batman film series with Batman Begins, the Spider-Man film series' The Amazing Spider-Man, Star Trek film series with Star Trek (2009) and The Pink Panther (2006) and The Pink Panther 2 (2009). In television, the 2004 TV series Battlestar Galactica was termed a "reimagining" of the original 1978 series.

 

Stand-alone sequels

 When sequels are set in either the same universe or one very similar to that of their predecessors yet have very little if any connection to said predecessors, then the work is referred to as a stand-alone sequel. Examples include the films This Is 40, promoted as "the sort-of sequel to Knocked Up." Evan Almighty is the sequel to the 2003 film Bruce Almighty, although only a small number of members of the original's cast actually return - and make little to no mention of the ones who do not. Events in the first film are treated as mostly irrelevant to second's events. Ghost Rider: Spirit of Vengeance is another example, debated by fans as being in either the same universe or a similar one to the 2007 film Ghost Rider, given that the two films don't play by all the same rules or acknowledge all the same facts, yet loosely view each other as part of the same basic mythos. Even so, the latter is set up so that it is not necessary to watch the former to make sense of the latter.
