Karen Gillan's departure from Doctor Who after two years as the Time Lord's sidekick Amy Pond will mean tears, the actress has warned fans.
Gillan will bow out in the fifth episode of the current series, to be shown in October, along with her on-screen husband Rory, who is played by Arthur Darvill.
The actress said she was glad to be leaving in an episode starring the Weeping Angels, and praised show supremo Steven Moffat.
The scary stone angels were recently voted the best-loved monsters in Doctor Who, ahead of the Daleks, in a Radio Times online poll of fans.
Gillan said: "Steven has written such a fantastic ending, I expect tears."
Moffat said there would be "tragedy" in the episode, adding: "It is a heartbreaking farewell to Amy and Rory.
"We see the Doctor and his little Amelia Pond race through the streets of Manhattan to save Rory with help along the way as River Song charges back on to our screens just in time to say goodbye."
This series also sees the return of the Time Lord's military allies on Earth - the members of UNIT - who made their first appearance in 1967.
UNIT, short for Unified Intelligence Taskforce, is now led by Kate, played by Jemma Redgrave, and makes its return in the episode The Power Of Three on September 22.
Matt Smith, who plays the Doctor, said that was "for the fans".
He said: "I think they like cyclical things and we have a good story. It was great to do an episode with UNIT and I hope the true fans like it."
Gillan is replaced as the Doctor's companion by former Emmerdale star Jenna-Louise Coleman who has already made a surprise appearance in the first episode of the latest series.
