"One Step Beyond" claimed in each episode that the stories you are watching are based on true accounts. However, I noticed this episode equivocated a bit and used words like 'may' and 'probably'. Well, if you ask me, it's all a lot of crap. Well written and interesting
but crap. David Opatashu plays a bellboy, Gerald Perkins. He works in a hotel San Francisco and it is 1906—the same year of the great earthquake. However, something odd happens several times—he sees and experiences the earthquake BEFORE it actually occurred. Unfortunately, this precognition didn't help as everyone thought he was a nut and didn't listen to his repeated attempts to warn everyone. Ultimately, the quake did come just as he predicted.
Aside from the fact that I don't believe any of this story, I noticed that the show repeated a common myth—that animals somehow know a quake is coming and they run long before it arrives. This isn't true, of course. But, if you ignore all the misinformation, the show is interesting and Opatashu turns in another fine performance—as he nearly always did on 1960s TV. Worth seeing but crap.
