Matthew McConaughey told Late Late Show host Ryan Tubridy about working with Irish actress Brenda Fricker, describing her as "intense".
The Hollywood star was interviewed on this week's show as part of his promotion of his memoir, Greenlights, which promises to provide fans with a detailed account of his often colourful life.
McConaughey and Fricker crossed paths when they worked together on A Time to Kill, a 1996 American courtroom crime drama based on John Grisham's 1989 novel of the same name.
