Voyage to the Bottom of the Sea: "Eleven Days to Zero" (September 14, 1964)
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).
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.
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.
