"Fallout" has become a massive hit for everybody with a Prime Video subscription, so much so that "Fallout" Season 2 is already on the way. Nobody really knows what’s in store for the characters, beyond a trip to New Vegas, least of all the actors that play them, but that seemingly won’t be too different from the way filming the actual series was handled, as Ella Purnell says the "Fallout" stars didn’t even know what was coming for their characters from one episode to the next. Sometimes it's due to scripts being rewritten until the last minute, sometimes it’s due to attempts to keep secrets to avoid leaks, but it’s become common practice for actors to not see parts of their script until necessary. Ella Purnell tells THR this was the case for "Fallout," one of the best Prime Video shows, which resulted in her not knowing what her own character’s story would be, and how she would relate to Walton Goggins’ Ghoul until the very end.
