Irwin Allen, praised in some circles as a science fiction genius and damned in others as a shameless schlockmeister, produced and directed this fanciful TV-movie. Set in the 21st century, the film concentrates on a group of colonists dwelling in a modernistic underwater city called Pacifica. The emphasis is on drama rather than special effects, as we see the deep-sea denizens struggling to cope with the pressures of their new existence--and their own personal animosities. Stuart Whitman heads a large cast of TV veterans, including Time Tunnel regulars James Darren, Robert Colbert and Whit Bissell, and onetime Voyage to the Bottom of the Sea star Richard Basehart (as the US President). Expanded from a short "demo" pilot film, City Beneath the Sea is the one Irwin Allen project that could have matured into a truly worthwhile TV series; unfortunately no network was interested in subsidizing this expensive effort.
