Evan Zweifel gave me a copy of this magazine as a present!
In his blog, Fred Pohl wrote about how Heinlein’s agent gave permission for Pohl publish the novel in If and to cut “five or ten thousand words in the beginning that were argumentative, extraneous and kind of boring” (and Pohl agreed to pay full rate for the cut words). But apparently, Heinlein “went ballistic” when he saw the first installment, so much so that when the book appeared as a separate publication, Heinlein made sure people knew who was responsible for the previous cuts by adding a note* that “A short version of this novel, as cut and revised by Frederik Pohl, appeared in Worlds of If Magazine.”
* The version of
Heinlein’s note that Pohl recalled was much funnier than Heinlein’s actual note in
our timeline, but sadly, we have lost track of where we saw Pohl’s version.
In Heinlein’s first version of this novel, written in 1977, the middle third of the story takes place on Barsoom, but in the 1980 published version, Barsoom was replaced by a futuristic British Mars
Here’s the problem: Heinlein’s story “—All You Zombies—” was the last word on one specific kind of time travel story: The story is which there is but one timeline. If you travel to the past and do something, it is because you traveled to the past and did that thing. But the Spierig brothers completely missed this point by introducing an older version of the Unmarried Mother who has newspaper clippings of other timelines that he has changed. The nice closed sexual loop is still present in the movie, but that wasn’t enough to stop my disappointment at the drubbing that the central story idea took. I wasn’t so hot on the music either (except for “I’m My Own Grandpa”), but the relationship between the Barkeep and the Unmarried Mother was spot on as was the depiction of time travel and the foreshadowing.
