Synopsis

At Deep Space Nine, a space station located next to a wormhole in the vicinity of the liberated planet of Bajor, Commander Sisko and crew welcome alien visitors, root out evildoers and solve all types of unexpected problems that come their way.

Several actors also directed episodes, including Avery Brooks, who directed and starred in the critically acclaimed episode "Far Beyond the Stars".

DS9 was the first television series in the Star Trek franchise to use computer-generated imagery (CGI) for exterior space shots.

Although a few other television series, such as Babylon 5, were using CGI exclusively to avoid the high expense of model photography, the Star Trek franchise continued to primarily use physical models for exterior space shots because producers decided models provided more realism.

DS9 continued using models where needed, such as the fourth-season premiere and the alternate-universe episode "Shattered Mirror".

Piller initially served as second executive producer and showrunner, but left the series in 1995 to manage Star Trek: Voyager.

Writer Ira Steven Behr was promoted by Berman to replace Piller as showrunner and held that role for the remainder of the series.
