In an exclusive interview with RTÉ Entertainment Domhnall Gleeson revealed that he and his brother Brian are writing a six-part comedy series. They hope to both star in the series should it be picked up.

Domhnall told RTÉ Entertainment: "I'm writing with Brian, and my friend Michael Moloney, and we're writing something that we're hoping to be making with Channel 4; just a six-part half hour series."

Michael Maloney worked as a writer on the sketch comedy program Your Bad Self in which Domhnall starred. Though Domhnall remained fairly tight-lipped about the premise of the series, he revealed his excitement about working in comedy: "I'd like to keep doing funny stuff, I think if I was going to do something it would have to be funny, the drama thing I adore but trying to work on something that's funny keeps you alive."

From an immensely talented family, Domhnall and Brian are the sons of acclaimed Irish actor Brendan Gleeson. This will be their third major project together, having previously co-stared alongside their father in a 2015 production of Edna Walsh's The Walworth Farce and appearing in their father's directorial debut short film 'Psychic'. Their brother Rory wrote the short film and released his debut novel Rockadoon Shore in 2017.

Domhnall and Brian Gleeson both grew up in Dublin. Younger brother Brian Gleeson is best known for his role in RTÉ television drama Love/Hate. His role as Hughie "Cueball" Power brought him an Irish Film and Television nomination for Best Supporting Actor. More recently he starred as Jimmy in the 2016 historical drama miniseries Rebellion and its 2019 sequel series Resistance.

Domhnall Gleeson appeared in a variety of film, television and theatre roles after graduating from Dublin Institute of Technology, where he studied Media Arts. At only 23 years old he was nominated for a Tony Award for his role in the 2006 Broadway production of The Lieutenant of Inishmore, before making his film breakthrough with his portrayal of Bill Weasley in the Harry Potter series. He has gone on to score starring roles in acclaimed films including dark comedy Frank, and sci-fi thriller Ex Machina, in addition to supporting parts in Star Wars and The Revenant. Currently, he is filming Peter Rabbit 2, in which he stars as Thomas McGregor.

Back in 2014 the brothers appeared together in a music video for Dublin band Squarehead's song '2025'. It also features childhood home videos of the two brothers, and was made in support of Domhnall Gleeson and Michael Maloney's comedy-sketch fundraising campaign Immaturity for Charity.
