The film's detailed miniature for the submarine Seaview and the amazing, high-tech, live-action sets were put into storage afterwards, and by 1964, Allen took them out of mothballs for a new TV series starring Richard Basehart as Nelson, and David Hedison as Captain Lee Crane.
Voyage to the Bottom of the Sea then ran on ABC for four successful seasons and 110 hour-long episodes (most transmitted in color; but with the first season only in black-and-white).
But, around the time of the second season -- when the series went to color -- the accent moved away from action towards science fiction and fantasy, and the series began featuring aliens, leprechauns, mummies, "Frost Men" and sea monsters of all shapes and sizes. Season Two also introduced another amazing vehicle to the program, the fantastic "Flying Sub."
In this case, instead of dispersing dangerous radiation from the Earth's atmosphere, the Seaview -- "the most extraordinary submarine in all the seven seas" -- is required to avert another planetary emergency.
But brilliant Admiral Nelson (Basehart) quickly develops a plan called "Operation Counter Force" with the help of nuclear engineer Fred Wilson (guest star Eddie Albert).
Specifically, the Seaview will detonate a nuclear device at the North Pole, thereby setting up "opposing lines of force" and "breaking the back" of the enormous tidal wave.
Before long, the Seaview has set sail with its new captain, Lee Crane, at the helm. Unfortunately, agents of a "hostile" foreign force would prefer to see America and Great Britain decimated, and they make every attempt to prevent the Seaview from accomplishing her critical mission.
On the way to the North Pole, the Seaview is dogged by an enemy submarine, rattled by depth charges, and ambushed by drone plane attack. Meanwhile, the hard-nosed Crane must prove his worth to the suspicious crew of Seaview, "highly skilled experts" each and every one.
Again, all this occurs in the first five minutes of the show...
In particular, the Seaview bridge (with visible ceiling, no less) is an impressive-looking set even by today's standards, and it appears to be manned by more than the typical TV skeleton crew, as you can see from the accompanying photo.
It's funny, but in a lot of outer space dramas, the main spaceship always boasts roomy corridors, and relatively few extras on screen at any given point...a visual misstep which seems to go against reality.
In the final frontier -- as under the sea -- space would surely be at a premium, and a fully manned vessel would seem like...well, a fully manned vessel, not a sparsely-attended hotel.
The result of this approach is that "Eleven Days to Zero" moves fast and is actually even sort of gritty in presentation, with the clock ticking down to doomsday, and the threat of death ever-present on all legs of the doomsday mission.
To wit, "Eleven Days to Zero" is a cinematic, action-packed pilot, yet it is decidedly humorless, and the characters - though undeniably heroic -- also lack much in terms of individuality and color. In that regards, series such as Star Trek are plainly superior.
I watched this show in reruns as a kid in the 1970s and, honestly, enjoyed it as much as if not more than Lost in Space.
What appealed to me as a child is what appeals to me about the show now: the amazing, retro-high tech futurism of the 1960s vehicle designs (particularly in the case of the Flying Sub and the Seaview) and the steadfast focus on action, action, action. I've always been a sucker for stories about submarines and their crews (hence my fascination with Captain Nemo and 20,000 Leagues Under the Sea...), and Voyage to the Bottom of the Sea still sparks the active imagination with abundance.
In the 1990s, Steven Spielberg embarked on a variation of Voyage to the Bottom of the Sea called SeaQuest DSV (1992-1995). It also began with a focus on hard-tech, adventure and "marine research" and then, in its second season, began featuring underwater Greek Gods, giant sea monsters, aliens and the like.
Voyage to the Bottom of the Sea set that identical course first, nearly thirty years earlier, so it is odd to say the least that SeaQuest didn't learn from its predecessor's missteps.
