7:30 8:00 8:30 9:00 9:30 10:00 10:30 11:00 11:30 Manville shifts to TV comedy in ‘Mum’

If Lesley Manville’s Oscar-nominated portrayal of an icy, unyielding family gatekeeper in “Phantom Thread” sent shivers down your spine, “Mum” is the antidote.

In the U.K. sitcom available on streaming service BritBox, Manville plays the polar opposite of her film role, a gentle soul with never a harsh word to say. It’s further proof of the actress’ shape-shifting artistry that has made her a favorite of top directors and actors.

Let’s name drop: Daniel Day-Lewis, the triple Oscar-winning star who played opposite her in “Phantom Thread.” The film’s acclaimed director, Paul Thomas Anderson. Mike Leigh, another singular filmmaker, who has featured Manville repeatedly, including as a faithful wife in “Topsy Turvy” and damaged woman in “Another Year.”

For good measure add Jeremy Irons, her co-star in a production of “Long Day’s Journey into Night” coming to New York’s Brooklyn Academy of Music May 8-27 after a heralded London run.

All that achievement and yet Manville is as warm — if far more spirited — than Cathy, her character in “Mum,” which debuts its second season on May 13, Mother’s Day. But she’s not a match for Cathy’s “miraculous” tolerance, the English actress insists.

“If there was an emoji that depicted Cathy, it would just be one big heart,” she said. “She allows people to be what they are. That’s a great thing, really, and something I probably fall short of in my own life. She allows people to come to their own conclusions about their own shortcomings or misgivings or bad behavior without judging them.”

Cathy, a recent widow and teacher’s aide, is tested by her loving but clueless adult son and his even more clueless partner (Sam Swainsbury, Lisa McGrillis). Her circle also includes a jolly brother and his snobbish girlfriend (Ross Boatman, Dorothy Atkinson), and a kindly longtime friend (Michael Mullen) who wants to be more to Cathy.

Each episode is titled for the month it takes place, as Cathy attempts to rebuild her life after her husband’s death.

Manville empathizes with Cathy’s new challenge of single motherhood. While the character takes on the challenge late in life, the actress said she had the task of bringing up her son, Alfie Oldman (from her short-lived marriage to Gary Oldman).

“I understand the delicacies and the dances that one needs to do around a teenage and 20-something-year-old son. They can be a tricky, delicate territory, and you have to be careful,” she said.

Manville holds the center steady in “Mum” as her costars spin around her with impeccable comic timing, especially Atkinson as social climber Pauline and McGrillis as self-absorbed girlfriend Kelly.

The ensemble’s byplay is so fresh that it seems certain improv must be involved. It’s not, said Manville, crediting the impression to how “brilliantly” her fellow actors perform and to the work of series creator Stefan Golaszewski.
