—I just re-read the source story. No actual trip to Mars. Covers little more than a city block, actually. And includes a second twist.—
I never read the book. I didn’t know that. Is the second twist in the new movie?
I own the old movie and actually enjoy it, once you get past the cheesy effects. And my firm belief is that, unless one believes in coincidence to the absurd, the whole movie is his Recall implant.
It’s a short story, a couple dozen pages or so. The implant, um, isn’t the interesting part...
