Deirdre O'Kane will play Robert Sheehan's mum in 'The Messenger'
She's fast becoming the ultimate TV mum.
Irish actress Deirdre O'Kane has joined the cast of The Messenger and is lined-up to play Robert Sheehan's mother in the Hollywood flick.
Viewers have seen Deirdre play Debra Moone in Chris O'Dowd's hit Sky series Moone Boy in recent years, and now she has happily stepped into another parenting part.
"I've shot a week already and I'm back for a couple of days on set this week," 45-year-old Deirdre told the Herald.
Production on the film is under way in the UK, and Dundalk-born Deirdre has been hanging out on set with former Love/Hate rogue Robert as well as her other latest co-stars Lily Cole, Jack Foz, David O'Hara and Tamzin Merchant.
It is Deirdre's third time working alongside Portlaoise actor Robert.
"I'm the mum of the younger Robbie, mercifully," Deirdre said.
"We've worked together on Bittersweet and Killing Bono, so we go back a long way."
The Messenger tells the story of a troubled man who sees ghosts.
It is written by Andrew Kirk, and Bafta and Emmy-winning director David Blair has taken the helm of the project.
"I'm thrilled to be involved and work with director David too. I've admired him for a long time," said mother-of-two Deirdre.
Although she's largely based in the UK, she will be back on Irish shores next month for a gala screening of Noble, the biopic about children's charity campaigner Christina Noble and her work in Vietnam.
The premiere will take place in Dublin on September 11.
Shot in Saigon last year, Noble was directed by Deirdre's husband Stephen Bradley and features well-known names such as Downton Abbey actor Brendan Coyle, Love/Hate's Ruth Negga and Liam Cunningham.
It scooped awards at a string of festivals over the past year and won the Audience Award at the Galway Film Fleadh last month.
