Loaded with cryptic imagery that defies straightforward interpretation in the traditions of linear storytelling, the series finale confounds viewers to this day. In interviews given years later, McGoohan claims the outcry over this finale led to the end of his career as a writer or actor in the UK.

Starring Charlton Heston and Roddy McDowall, 20th Century Fox’s big-screen release of Planet Of The Apes quickly becomes one of 1968’s movie success stories, and easily one of the year’s two most influential genre films. Propelled into the future aboard a spacecraft from Earth, a trio of astronauts find themselves on a world ruled by sentient apes with no love of humanity whatsoever – for humanity nearly destroyed their world. The studio almost immediately sets the wheels in motion for a sequel.

For the second year running, NBC makes an announcement over the closing credits of Star Trek, reassuring viewers that NBC has picked up the show for a third season. Where the second season’s renewal was brought about by a substantial fan letter-writing campaign (with guidance from Gene Roddenberry), the third season pickup comes after fans stage protest marches outside NBC’s headquarters in Burbank and New York, having gotten word (from Star Trek fan Bjo Trimble, by way of Roddenberry) that the series is likely to be cancelled. The renewal is a double-edged sword, however: in the fall, NBC will move the series to Friday nights, a time slot where it’s virtually guaranteed to be cancelled at the end of its third season.

The Soviet Union launches an unmanned test flight of the Soyuz 7K-L1 command/service module, a spacecraft intended to orbit the moon with cosmonauts aboard. This unmanned flight, however, is designated Zond 4, and on its way back into Earth’s atmosphere it loses attitude control. With no precision guidance to ensure that Zond 4 will land on Soviet soil, Russian space authorities command the vehicle to self-destruct in mid-air to prevent their space technology from falling into another country’s hands. (The image accompanying this historical entry is computer-generated, and not a real photo.)
