“Mad Men” creator Matthew Weiner told trade paper Variety Thursday that he “hopes” his new series for Amazon, “The Romanoffs,” will launch on the streaming service in the spring of 2018.

In his first extended comments on his new series, he offered a few other details on the anthology, notably that each of its eight hourlong episodes will stand alone with a contemporary setting about people who believe they are descendants of the Russian imperial family, who were slaughtered by the Bolsheviks in 1918, the year after the Russian Revolution.

Weiner’s idea appears based on century-old speculation — or rather the persistent urban legend — that Czar Nicholas II’s youngest daughter, Anastasia Nikolaevna, survived the execution of her family and later escaped. Weiner didn’t elaborate on individual episode plot lines, or whether the show’s characters believed they had descended from Anastasia.

But clearly Weiner’s new series is meant to be fiction. “I liked the idea of telling a story in a format where you don’t have the serial element — you have to commit to a resolution,” he said. “The escalation has to happen within the story — nothing is carried over from one episode to another. As a writer, that’s an exciting idea.”
