Courtesy of i09... here's a clip from an upcoming new documentary titled The Captains, in which William Shatner aka Captain James T. Kirk, interviews every actor who has played captain in any of the series in the Star Trek franchise. Interesting concept, especially if you're a fan.

The documentary, produced and directed by William Shatner, will air on July 22 at 8PM EST EST on EPIX and EpixHD.com.

In the below clip, Shatner chats with the incomparable Avery Brooks who played Benjamin Sisko on Star Trek: Deep Space Nine - the first African American captain to lead a Star Trek series.
