So, basically, the film [Patton] is about a fictional character whose life is strongly inspired by Patton's, but who clearly isn't him... Everybody finds it normal, fudging reality to make a screenplay more dramatic.
Has there ever been a biographer who did not dream of writing, "Jesus of Nazareth used to lift his left eyebrow when he was thinking"?
What Binet reveals, though, is how our understanding of any story necessarily depends on embellishing the historical record. Both the author and the reader contribute to the embellishment. For example, Binet knows the difference between Czechs and Slovaks because of tennis. "Ivan Lendl was Czech while Miroslav Mečíř was Slovak." His sense of their playing styles informs his impression of the character of the two assassins. (He later knows one of the smaller Czech towns because the hockey goalie Dominik Hašek is from there.) He imagines the creaking of the tram outside of Jozef Gabčík's room because he has spent time in Prague.
In addition, the author inevitably shapes the story into a narrative by choosing what information to include.
I can't tell this story the way it should be told. This whole hotchpotch of characters, events, dates, and the infinite branching of cause and effect—and these people, these real people who actually existed. I'm barely able to mention a tiny fragment of their lives, their actions, their thoughts.
Binet regularly equivocates over whether to include particular incidents, based on whether they are relevant or well-attested. Meanwhile, he quietly includes true facts that provide verisimilitude:
The Sten was concealed in a bag that Gabčík had filled with dry grass... If the police checked him, how would he explain the fact that he was walking around town with a bag full of hay? Well, actually, that's easy: all he'd have to say is that it's for the rabbit. In those days, many Czechs bred rabbits at home in order to improve their daily diet, and fed them on grass taken from the city's parks.
No matter how much we know about a person or event, we still need to apply our experiences and assumptions to make it into a compelling narrative.
Despite its dark subject matter and postmodern trappings, HHhH was entertaining and informative.
