premiere 就是指电影“首映”。大片的 global/world premiere（全球首映）常会吸引众多影迷的目光，例如：

The highly-anticipated Transformers: Revenge of the Fallen opens for Chinese audiences with a special midnight screening Wednesday, to coincide with the film's global premiere.

　　此外，一部影片公演前有时还会为试探观众反应而进行 preview（试映），然后才开始在各影院 exhibition（正式放映）。

平时我们还常用 debut 来表示（演员、运动员）首次亮相；初次登台（或上场），例如：

In 2002, the band members reformed as Maroon 5 and released their debut album Songs About Jane.

在2002年，乐队进行重组，成立了Maroon 5，并发行了他们的首张专辑《Songs About Jane》（珍·情歌）。
