The Night of the Human Trigger

Some of the frames in the earthquake scene near the end originally appeared in Die Eroberung des Weltalls (1955), Ross Martin's film debut. In that film, the quake occurs on Mars near the end of the movie.

At the opening, Artemus and Jim are standing at the hitching post in a deserted town, where Artemus finds a flyer that warned the citizens to leave town before the sun is "at its summit" on June 5. Artemus comments that it's the fifth, and looks upward at the sun, saying, "And guess where that sun is," prompting Jim to look upwards at the sun too. Then they walk away from the hitching post, and the sunlight is coming almost directly in front of them, casting long shadows as it only would at sunrise or sunset.
