The latest production from stars Holliday Grainger and Harry Treadaway enjoys a larger cast than usual – thanks to the recent arrival of twins.
The adoring parents were spotted strolling with their newborn babies last week in Devon, where they moved shortly after Holliday learned she was expecting.
Last September, The Mail on Sunday revealed that work on the second series of its hit BBC drama The Capture had been put on hold due to her pregnancy.

However, it was not known until now that the 33-year-old, who also stars in the TV adaptations of JK Rowling’s Cormoran Strike novels, was expecting twins.
For Harry, who played Princess Margaret Roddy Llewellyn’s baby boy in The Crown, the new arrivals are a very special occasion as he is an identical twin himself.
The couple cradled the babies in papooses to protect them from the elements while they window shopping before eating lunch at a small cafe.

“It was a beautiful and happy family outing,” said one spectator.
“Even though both actors are on our TV screens all the time, no one has paid them any attention. But the twins received a lot of admiring comments from groups of old ladies. Mom and dad seemed delighted with this.
Holliday and her actor boyfriend have been dating since 2015.

Holliday plays Detective Inspector Rachel Carey in The Capture and plays Robin, Strike’s sidekick in the private investigator series.
Meanwhile, Harry, 36, will soon appear as a detective in My Name Is Lizzie, the Channel 4 miniseries about the failed undercover operation in the 1992 murder of Rachel Nickell on Wimbledon Common.
Her identical twin Luke is also an actor, recently seen in the ITV drama The Singapore Grip.

Daddy Harry is a twin himself – so did that make things more likely?
Harry Treadaway, pictured here with his twin Luke who smokes cigarettes, may think having two babies together is a family tradition. But experts say her genes are unlikely to have played a role.
It is not known whether her children are identical or not. According to the NHS, a third of twins are identical, caused when a single egg is fertilized and splits in half. Such “monozygotic” twins are not familial and everyone has the same chance in 250 of having them.
Non-identical “dizygotic” twins occur when two separate eggs are fertilized. The resulting babies are no more alike than all other siblings.
There is a gene that makes a woman more likely to release two or more eggs during ovulation, which is common in families. Whether the father carries this gene does not affect whether he will have twins, but he could pass it on to a daughter, leading to the idea that the twins are “skipping a generation”.
