It would be so funny if a perfectly serious and fundamental scientific invention were used exclusively for profit. That’s exactly what Harry Harrison showed us—what will happen if a time machine ends up in the hands of people who think only about their own pocket. Without stopping at anything, American filmmakers “wring the sweat” from this marvelous device, forcing it to serve the needs of movie production. Cause-and-effect relations, anachronisms, the “butterfly effect”—everything moves into the background. The main thing is to make the film, and, of course, to cut from it your own harvest in the form of recognition and profit.
