Amazon spent a couple of years trying to make its Citadel spy series take flight, with more than one spin-off now available to view on Prime Video if you're keen, but a new teaser trailer suggests that it could be moving onto new ideas. That, or it might just be trying to diversify its spy offering.
Whatever the strategy might be, the outcome is Butterfly, a new series starting on Prime Video on 13 August, in just about a month's time. It stars Daniel Dae Kim and Piper Perabo as a father and daughter reunited afters years in which David, the dad, was forced to maintain secrecy about even being alive.
