One of the people in charge of keeping the TV show authentic was studio design director Emil Pagliarulo, a Bethesda veteran who’s been closely involved with the Fallout series since its breakout third instalment, released in 2008.
He tells Newsbeat there was an early decision to keep the TV show “canon” – that would become a guiding principle.
That meant “everything that happens in the show happened in the games, or will happen in the games,” says Emil.
Fallout, first launched in 1997, has a deep well of established lore the series’ biggest fans know well and feel protective of.
Emil admits there was some “back-and-forth” between the TV and gaming sides, especially earlier on.
“It’s difficult because TV’s an entirely different medium,” he says.
“It’s really about getting the tone right, but they were very respectful of where we wanted to take it.”
He says the strict adherence to the video games’ timeline did result in the “occasional late-night text” from the TV show’s set.
“Hey, we’re filming tomorrow, we had this question,” recalls Emil.
“Is this… canonically right?”
“It was always a back-and-forth. It’s really fun.”
