This documentary is a series of interviews, actually conversations, between iconic actor William Shatner and the other actors who have played Star Trek captains. Jetting around the country, Shatner talked with Patrick Stewart, Captain Picard from Star Trek: The Next Generation, Avery Brooks, Captain Sisco from Star Trek: Deep Space Nine, Kate Mulgrew, Captain Janeway from Star Trek: Voyager, Scott Bakula, Captain Archer from Enterprise, and Chris Pike, Captain Kirk from the 2009 Star Trek movie.

Interspersed with the interviews were clips from a Star Trek convention Shatner appeared at in Las Vegas, where he met other Star Trek actors, including Rene Auberjonois, Jonathan Frakes, Robert Picardo, Connor Trinneer, and Nana Visitor, among others. Shatner also had a short interview with his old friend Christopher Plummer for whom he understudied at the Shakespeare Festival in Stratford, Ontario early in his career and who played the villainous Chang in Star Trek VI: The Undiscovered Country (1991). The only really obvious omission was Leonard Nimoy.

This documentary was fascinating in how it revealed as much about Shatner as his subjects. Topics ranged from how they got started acting, to how each actor got their Star Trek role, to how the Star Trek experience changed their lives and affected their families, to philosophical musings on death, and many things in between. Most of the captains are classically trained stage actors who weren't necessarily immediately onboard with playing a science fiction character for TV. Bakula and Brooks both have extensive musical backgrounds, Bakula as a singer and Brooks as a jazz pianist. In fact, Brooks provided the documentary with a pleasing smooth jazz score.

All of the captains came off as intelligent, hard working, and frank. It was nice to see that they all still took their roles seriously and were truly humbled by the fan reactions to their work. Shatner, especially, seemed genuinely moved when he found out that the Canadian head of Bombardier Aerospace was inspired to take up aerospace engineering from watching Shatner on Star Trek. There was also a poignant scene at the convention where Shatner greeted a young wheelchair-bound man whose devotion to Star Trek seemed to be about the only thing that kept him going.

The interview with Stewart seemed to have the most resonance. It was obvious that there was genuine rapport between him and Shatner. When they talked about how the long hours playing their roles negatively impacted their marriages, it was heartbreaking. Mulgrew's take on being a single mother during her tenure as captain was also touching.

Shatner turned out to be an excellent interviewer. He kept things light and often humorous, such as when he conducted Pine's interview at a card table on a busy intersection or when he met Mulgrew sitting in a cardboard box. This allowed him to get his subjects relaxed and able to open up about some of the deeper questions. Shatner used his personal experiences to draw out measured responses from the other captains. Shatner has a reputation for being egotistical and antagonistic, but none of that was evident here. Maybe time has mellowed him out.

The Captains is a journey of discovery for Shatner that is an enjoyable look at the world of acting in general and the Star Trek universe in particular. It is a sincere glimpse into the heart and soul of Star Trek.

Entertaining? Yes Informative? Yes. Self-serving to Shatner's ego? Definitely.

If you can get past Shatner's huge ego, then this is an enjoyable documentary. Obviously it's a must-watch for any serious fan, but casual ones will find it interesting too. Also, Shatner's questions, while long winded and self-centered, did elicit some great dialog from the other captains. I especially enjoyed the emotional chat with Patrick Stewart. I was particularly surprised with the Christopher Plummer appearance. Then the tables turn and they ask the Shat questions. Sadly, you kinda get to understand why some of the other characters complained about him over the years.

Also, it never really occurred to me the intense commitment and time it takes to be the captain, or the toll it took on their family lives. And, you might be concerned for Avery Brooks, although my Rutgers friends say that theater professors are often like that...

Even some of the most enthusiastic Trekkies do not quite understand the unprecedented success of the original Star Trek as created by Gene Roddenberry. The original show, as we all know, ran only for three seasons in a far less literate world. However, its impact was such that it was followed by five successor series, eleven movies, a mountain of merchandise, and a multi-billion dollar industry collectively known as the Star Trek franchise (currently owned by CBS Television Studios, which now owns television properties previously held by Paramount Pictures.

There is only one reason for this, and creative people in the entertainment industry like Rod Serling and Frank Capra who also left legacies on par with Gene Roddenberry, knew the reason. Much like Samuel Taylor Coleridge's Rime of the Ancient Mariner and other literature at that level their stories spoke to the sanctity of the human soul and the problems of human progress on Earth. As in the case of Rod Serling's The Twilight Zone, it masked these problems in allegorical science fiction in order to slip them through entertainment suits whose primary interest is in making money.

Although in his fine documentary, The Captains, William Shatner barely touches on this core mission of Star Trek, his purpose for making the film was to come to terms with the role of Captain Kirk and his latter day realization that it was not a frivolous role, nor superficial. Sir Patrick Stewart is also on hand to help him in this realization.

Along with the engaging backgrounds of other Star Trek Captains, all who came from fine backgrounds as actors, Shatner acknowledges that the role, along with the series, was life changing to millions. Many of the ardent followers of the Star Trek phenomenon are people like the rest of us. We all live a daily life of struggle. Here, show business people whose sole purpose was not just to make money but to make life, pass on a little hope.
