Succession star Brian Cox will be among Ryan Tubridy's guests on Friday night's Late Late Show on RTÉ One and the RTÉ Player.
Sharing the news on his RTÉ Radio 1 show on Wednesday, the host said: "Brian Cox, who plays Logan Roy - the big, over-the-top, overbearing patriarch - will be joining us on the Late Late Show this Friday live in-studio.
"I am so excited to see him in the flesh.
"It will be very, very interesting to talk to him. What an actor he is."
Cox released his autobiography, Putting the Rabbit in the Hat, last year.
On Tuesday, it was announced that singer Melanie C will also be among this week's Late Late Show guests.
