This was my favorite TV series in the 1960s. While sometimes derided by serious Sci-Fi fans, Voyage was very successful in its day, and actually lasted a season longer than Star Trek. The casting of Richard Basehart was a real coup, and David Hedison, who turned down the Captain Crane role in the VTTBOTS movie, came aboard in the TV show. Featuring special effects that still hold up today, VTTBOTS originally started out as serious sci-fi, whose first season episodes still stand tall with the best of TV sci-fi. The second season brought color episodes, a re-designed Seaview, and a new invention, the Flying Sub, to help expand the action. As often happened with Irwin Allen's shows, writing became spotty as time went on. Solid sci-fi stories were often sandwiched between "monster of the week" shows. Even the cast was surprised when the show was picked up for a fourth season. From what I've read, Basehart was anxious to get out of the grind of a TV series, and frankly back into what he considered serious acting. So one will notice an episode or two where he's absent, or obviously being doubled (the episode with the giant sea spider and the hyper fast submarine was one where he was doubled, and he literally duped his lines). There's also another episode where Basehart's son John had a guest part (playing a crewman named "Johnson". Get it? John? Basehart's son?).
I had the pleasure of meeting David Hedison at a convention a few years back. He recounted many fine stories about Voyage, including his relationship with Basehart, working with Irwin Allen, and his years as Captain of the Seaview.
I have waited a long time for this to come out on DVD. I am glad to see it is finally going to hit the DVD shelves!
