KRONOS (1957 SciFi Classic -B&W-)

A giant asteroid nearly five miles wide crashes into the ocean near Mexico. A trio of scientists, led by Les Gaskell, investigate, and discover a giant machine. Meanwhile, a colleague of the scientists has been possessed by an alien electricity, and is controlling the actions of a 100-foot-tall robot, which is heading for Los Angeles and destroying all in its path.

'Spyros Skouros', then president of 20th Century Fox, liked the concept and reportedly urged the production of this film.

The long shots of Kronos moving were accomplished by animation, presumably the work of animator Gene Warren.

Before production began, the budget was cut. This required a second draft of the script which eliminated some character development and some expensive special effects sequences.

The communication console and screen from Klaatu's saucer featured in The Day the Earth Stood Still (1951) can be seen directly in the background of Labcentral's "Astro Physics" Laboratory where Vera Hunter and Dr. Hubbell Eliot have their confrontation. A map of the world has been placed behind the glass.

"M47" (Dr. Leslie Gaskell's designation in the movie for the so-called "asteroid") is in real life, one of the "missing" Messier Objects whose correct position was not definitively identified until 1959 (two years after the release of 'Kronos'). It is an open star cluster in the constellation of Puppis.
