Voyage to the Bottom of the Sea (Seasons 1–4)

Voyage to the Bottom of the Sea (1964) is the Cold War sci-fi series you can watch online on iFILM. At its heart sits the Seaview, a glass-nosed atomic submarine run by Admiral Harriman Nelson (Richard Basehart) and Captain Lee Crane (David Hedison).

Every dive turns into a new emergency. One week it's enemy saboteurs aboard; the next a mad scientist with a doomsday device, a giant creature rising from the trench, or a nuclear countdown nobody can stop. The crew puts out one fire after another somewhere between geopolitics and pure pulp. Created by Irwin Allen from his own 1961 feature, it ran four seasons on ABC from 1964 to 1968 and switched to color in its second year.

This is 1960s television at full tilt: rubber monsters, blinking consoles and a crew that saves the world on a weekly schedule. If you like your science fiction vintage and unironic, it lands easily. Stream every episode of Voyage to the Bottom of the Sea online on iFILM.
