There are no feathered wings in Sir Lenny Henry’s six-part BritBox series “Three Little Birds.”

The titular trio, Henry, 65, said in a Zoom interview from London, “are these three very empowered women leaving life in Jamaica for another life — a life of freedom in Britain in the late 50s.”

Its roots are very personal for the comedian-actor-writer who was knighted for his cultural contributions by Queen Elizabeth II in 2015.

“My mother Winifred passed away in 1998. Before she passed she told me lots of stories about coming to Britain in the ‘50s and what it was like for her.

“One of the things I always thought as a writer was anybody who watches this show, who is a fan of ‘Godfather II’ or ‘Avalon’ or ‘Moscow on the Hudson,’ will get this idea of what it means to leave one place, whether it’s because of danger and poverty and no protection, and go to another place where you might be able to survive and make a new life for yourself. All of the stories from my mom were about that kind of thing.

“What it was like. The racism when she got here. The sexism. As I dug deeper with the help of Russell T. Davies, who was my mentor in the early stages, we just uncovered more stories, more interviews and talked to more people and we realized that these stories are more common than we thought.

“So the idea of presenting ‘Three Little Birds’ as a rites of passage of three Black women coming to Britain in the ‘50s to start again felt like a very good thing to be doing. To present to the British public who’ve never really seen anything like this before. That was the inspiration behind it.”

While “Birds” is a fictionalized version of what happened, Rochelle Neil’s Leah is the stand-in for Henry’s mother.

“The starting point,” Neil said, “was just checking my blind spots. She’s a woman in the 1950s and obviously the point of views and the way that people were treated back then is slightly different to my point of view and the way I’m treated as a Black woman in the UK.

“Then I just kept deep diving into the mindset of the time, the era. Realizing just how courageous she was to travel, minus her husband, minus her children, to set up a new life.

“I had,” she added, “wonderful resource material: My grandmother wrote a memoir. I had a first-hand account of her life in Jamaica and the decision to move to the UK.”
