The "Dragon Ball Z" films comprise a total of 15 entries as of 2015. The first 13 films were typically released every March and July during the series' original run in accordance with the spring and summer vacations of Japanese schools. They were typically double features paired up with other anime films, and were thus, usually an hour or less in length. These films themselves offer contradictions in both chronology and design that make them incompatible with a single continuity. All 15 films were licensed in North America by Funimation, and all have received in-house dubs by the company. Prior to Funimation, the third film was a part of the short-lived Saban syndication, being split into three episodes, and the first three films received uncut English dubs in 1998 produced by Funimation with Ocean Studios and released by Pioneer. Several of the films have been broadcast on Cartoon Network and Nicktoons in the United States, Toonami UK in the United Kingdom (these featured an alternate English dub produced by an unknown cast by AB Groupe), and Cartoon Network in Australia.
