Jodie Comer said the upcoming series four of Killing Eve will be "one to remember" as the show comes to an end.
Production on the cat-and-mouse thriller, starring Jodie as Russian assassin Villanelle and Sandra Oh as former MI5 agent Eve Polastri, will begin in the early summer in the UK and across Europe.
The eight-episode series will premiere on BBC One and BBC iPlayer in 2022.
Jodie said : "Killing Eve has been the most extraordinary journey and one that I will be forever grateful for.
"Thank you to all the fans who've supported us throughout and come along for the ride.
"Although all good things come to an end, it's not over yet. We aim to make this one to remember."
Sandra Oh said: " Killing Eve has been one of my greatest experiences and I look forward to diving back into Eve's remarkable mind soon.
"I'm so grateful for all cast and crew who have brought our story to life and to the fans who have joined us and will be back for our exciting and unpredictable fourth and final season."
Sex Education's Laura Neal will take over as lead writer, following in the footsteps of Phoebe Waller-Bridge, Emerald Fennell and Suzanne Heathcote.
Waller-Bridge adapted the first series from Luke Jennings' Villanelle novels, but handed over the role of head writer to Fennell for the second series, before Heathcote took over for the third.

The show also features Fiona Shaw as MI5 boss Carolyn Martens and Kim Bodnia as Villanelle's handler Konstantin.
Sally Woodward Gentle, the show's executive producer, said: "We have been unbelievably blessed to work with extraordinary human beings throughout the life of Killing Eve.
"From the magical Phoebe via the delectable Emerald, super talented Suzanne and now mind blowing Laura; headed by the super-powers of Sandra, Jodie, Fiona and Kim, and with brilliantly talented directors and crew.
"No-one knew what an adventure we were embarking on and there's so much more to come. Buckle up."
