Star Wars legend Mark Hamill and Game of Thrones actor Liam Cunningham are among the guests on this week's Late Late Show.
Hamill will be chatting about being part of the popular movie franchise and what is was like filming along Ireland's Wild Atlantic Way.
The film icon will also tell Ryan about how Star Wars changed his life and what it was like returning to play Luke Skywalker decades later as the story continued.
Hamill was recently announced as the inaugural International Guest of Honour for this year's St Patrick’s Festival.
Liam Cunningham, who is also taking part in this year's St Patrick's Day Festival, will be in studio and will chat about the looming Game of Thrones finale.
He will also be sharing what he learned on a recent trip to Uganda and giving his thoughts on the scandals engulfing some of the charity organisations working in the developing world.
Cork woman Samantha Barry made headlines of her own earlier this year when she was appointed the new editor-in-chief of US magazine Glamour. She’ll be telling Ryan what it’s like to find yourself rubbing shoulders with Anna Wintour on the front row at New York Fashion Week and interviewing Donald Trump in a toilet in Miami.
Also, as Daffodil Day approaches, Ryan will be joined in studio by some of those who have contributed to or benefited from the fundraising and work carried out by the Irish Cancer Society.
