Cuckoo Season 6 - What We Know So Far

Though the previous season debuted as long ago as 2019, the BBC hasn't made any announcement regarding a return date for "Cuckoo."

Part of this is almost certainly the longer wait time between seasons of British television series compared to what U.S. TV viewers might be used to. Each season of "Cuckoo" has premiered about two years after the previous one, which is much slower compared to cable dramas and comedies Stateside that tend to produce a season a year.

The considerable wait between seasons has also likely been exacerbated by the worldwide COVID-19 pandemic, which has generally slowed down TV and film production up until very recently. Even if the BBC announced the show's return very soon, the production cycle would still mean it'd take about a year for "Cuckoo" to be written, produced, and filmed. At the earliest, we would expect a Season 6 of the series in late 2022.
