Despite the name, this isn't a period piece. Instead, it's a collection of eight stories about modern-era people who believe they're descendants of the last Russian royal family. The teaser trailer below doesn't reveal anything (it's mainly a reminder of Amazon's huge casting budget), but it's safe to say that there will be doubts about the lineage of central characters.

The Romanoffs will come relatively soon after Amazon's other giant series for the second half of the year, Jack Ryan, and epitomizes the company's recent take-no-chances approach to Prime Video series. It wants shows that are virtually guaranteed to get international buzz and critical acclaim, and it doesn't get much bigger than staging a Mad Men reunion with more famous names thrown in for good measure. Whether or not this strategy pays off is another story -- Amazon has certainly had success, but it's still relatively new to investing so heavily in lavish productions.
