co-feature

...It is also called a programmer in English. In other words, it is a second feature, supporting feature, or co-feature to the main feature film of a program. In the case of Japanese films, there were methods of bundling, such as a program of one modern drama and one period drama, bundling with older works, mixing with other companies' works, or using a low-cost film called the second part as a supporting feature, from before the war. According to Junichiro Tanaka (History of the Development of Japanese Films), after the war, around 1950, when the film famine at the end of the war, when people were starved for entertainment due to the proliferation of movie theaters and the dumping of already-released films, became a thing of the past, double features, which were called a service to the audience, began to become prominent.

*Some of the terminology that refers to "co-feature" is listed below.
