William Shatner has taken it upon himself to create a documentary about Star Trek, specifically focusing on the many captains that have spearheaded the series over the years. In The Captains, Shatner sits down for interviews with head honchos Patrick Stewart (The Next Generation), Kate Mulgrew (Voyager), Scott Bakula (Enterprise), Avery Brooks (Deep Space Nine) and Chris Pine, who took on the role of Captain Kirk in J.J. Abrams’ Star Trek reboot.

A trailer for Shatner's documentary has been released, and it’s pretty entertaining. The actor’s sensibilities are perfect as the host and star of the film, and the idea of interviewing each of the Star Trek captains is pretty genius. Plus, Shatner being Shatner, his reaction to a fan towards the end of the trailer is definitely a highlight. The Captains will premiere on July 21st on the cable channel EPIX HD.

Here’s the trailer:
