Colin Farrell, Margot Robbie, Michael Flatley, Conor Murray, Mary Robinson, and Kodaline’s Steve Garrigan will usher in the latest season of RTÉ's "The Late Late Show" on Friday, September 12.

Friday's show will mark the beginning of the third season with host Patrick Kielty at the helm.

Hollywood royalty, actors Margot Robbie and Colin Farrell, will meet up with Kielty to chat about their upcoming film "A Big Bold Beautiful Journey." They will share stories from set and their experience of working together for the first time.

Ahead of the Emmy Awards in Los Angeles this weekend, Farrell will chat about his nomination for "The Penguin," while Robbie will reflect on the global success of "Barbie."

Following his decision not to pursue the Irish Presidency, Michael Flatley will join Kielty to reflect on his decision and the reasons behind it. He’ll also speak about his personal journey with cancer and his involvement with a new exhibition by Breakthrough Cancer Research.

After hanging up his boots, Irish rugby legend Conor Murray will chat to Kielty about his new autobiography "Cloud Nine." He will reflect on a decorated career in Irish rugby, share stories from the dressing room and discuss how he found the strength to continue playing in the days and weeks after a road traffic collision left his father seriously injured.

Also on the lineup is former President of Ireland Mary Robinson, who will discuss urgent global issues, including the deepening humanitarian crisis in Gaza. She will share insights from her recent visit to the Gazan border and speak about the role of international leadership in what the UN World Health Organisation has declared a man-made famine.

"Late Late Show" viewers will also be treated to a special performance from Kodaline’s Steve Garrigan.

"The Late Late Show," sponsored by PTSB, airs on RTE One at 9:35 pm on Fridays and streams on the RTE Player.
