In the movie of Tom Wolfe's novel 'The Right Stuff' Annie was portrayed as a loving wife and John Glenn was portrayed as a loving husband... There is no doubt that these two were a loving couple... The sad part, during those years Democrat President Lyndon Johnston treated those astronauts like monkey's in a sideshow circus... John Glenn then became a Democrat. Sad but true... But Bubba Clinton gave him final ride to space for his support during his corrupt administration, so it worked out in the end for John Glenn... a Hypocrite to the end.
Glenn did not get as good a portrayal in the book as he did in the movie. In the book, his overly earnest "brown-nosing" goodie-two-shoes manner clearly irritated many of the other astronauts. His peers so clearly disrespected him that they basically voted him off the first flight (which went to Alan Shepard).
That did turn out to be fortuitous, for Glenn ended up being the first American in orbit on a later flight, which resulted in all the ticker tape parades and the full "JFK-Jackie" red carpet treatment.
The scene in the movie with Lyndon Johnson fuming outside the home of Annie Glenn during the flight, because she didn't want him in her house, was pretty funny.
