After the time mish-mash of Ijon Tichy’s seventh voyage, it wasn’t clear whether Ijon would ever ply the channels of time again, but here he is, traveling back in time to persuade himself to go forward in time and take up the helm of THEOHIPPIP—a.k.a. Teleotelechronistic-Historical Engineering to Optimize the Hyoerputerized Implementation of Paleological Programming and Interplanetary Planning. It takes a few attempts for older Ijon to convince younger Ijon to head to the future on a one-man chronocykl, but when he does, the younger Ijon begins the unexpectedly hard task of righting history’s wrongs. As a sophisticated time traveler yourself, you’ll spot what’s happening early on, while you also get a tour of history from the formamtion of the Solar System to the extinction of the dinosaurs and the paintings of Hieronymus Bosch. You’ll also recognize the fun Lem has at the expense of the bureaucracies of mid-20th-century Poland.

Sure, others have pulled that 20th century actress forward to make modern films with spectacular failure, each attempt spawning a branch universe unconnected to the 21st century of time traveler Det Gruber, but none of the others took into account the psychological factors in the way that Det’s employers have done.

As a test to determine whether humanity should be destroyed, four slimey aliens grant schoolteacher Neil Clarke the power to do absolutely anything. I kinda think that if I had that power, and I made as many mistakes as Neil, I'd be using my power to rewind time more often than he did.

Writer and director Terry Jones acknowledges H. G. Wells’ “The Man Who Could Work Miracles” as inspiration for the story.

The prologue to the third Max Einstein book tells us that twelve-year-old genius do-gooder Max traveled as a baby from 1921 to the early 21st century when an experiment in her genius parents’ basement went a little ca-ca. Later on, Einstein himself makes a cameo appearance, possibly by opening some kind of communication line from the past to Max in her moment of need, but nothing else crops up in the way of time travel. I suspect that a truly genius rebel child would toss this aside as being condescending, preachy, one-dimensional, and melodramatic (not in a good way), as well as innacurate in most of its science and guilty of oversimplifying complex world problems.

You head out on a quick, rollicking ride back through time, with an unknown pursuer and an ambiguous conclusion.
