Needing no introduction, Dublin native Brendan has earned his acting chops in dozens of iconic films and TV shows over the years including "The Banshees of Inisherin", "In Bruges", "Mr. Mercedes" and most recently made an appearance in "Joker: Folie à Deux".

Now 69, the Emmy winner started acting in his thirties, making his debut in the 1990s drama "The Field".

Some past Irish pupils might also remember first encountering Gleeson during their school days, with the esteemed actor appearing in a short film as Gaelige: 2001’s "Cáca Milis".

Following in their father’s footsteps, the Gleeson family clearly has acting in their blood with the sons of the "Harry Potter" star going on to carve out successful acting careers of their own.
