Jack Gleeson: From Royal Pain to Brewing Sensation

It's been over a decade since the world witnessed the rise and tragic fall of Joffrey Baratheon, the infamous tyrant king from HBO's smash hit series Game Of Thrones. The role catapulted 18-year-old Jack Gleeson to stardom, but it also took a toll on his mental health. In an unexpected twist, the Cork-born actor has resurfaced with a new, more mature persona in Netflix's House of Guinness, leaving fans and critics alike wondering what happened during his nearly decade-long hiatus.

Gleeson's journey from child star to troubled young adult is a fascinating tale of fame, self-discovery, and perseverance. As we delve into the life of this complex actor, one thing becomes clear: Jack Gleeson is not your average celebrity. Unlike his peers, who have struggled with addiction, mental health issues, or public scandals, Gleeson chose a different path – one that led him to question the very nature of fame.

Jack landed the role as evil King Joffrey in Game Of Thrones (pictured in 2011 with co-star Sophie Turner as Sansa) at the age of 18, but later shunned fame for a quieter life

In 2014, at the tender age of 21, Gleeson shocked the world by announcing his retirement from acting. The reasons behind this decision were shrouded in mystery, with some speculating that it was due to the public's negative reaction to his character. However, in a candid interview with Entertainment Weekly, Gleeson revealed that he simply didn't enjoy acting as much as he used to.

"I started acting when I was eight, and really, really loved it... For some reason, it became a bit mechanical and less kind of passionate when I started Game of Thrones." He added, "When you make a living from something, it changes your relationship with it. It's not like I hate it, it's just not what I want to do."

Gleeson's decision to leave the spotlight wasn't taken lightly. He had already achieved incredible success, including two Screen Actors Guild Award nominations for his portrayal of Joffrey Baratheon. However, as he delved deeper into the world of acting, he began to feel suffocated by the constant attention and scrutiny.

In a 2014 address to the Oxford Union, which became a viral hit with over 3.5 million views, Gleeson blasted the celebrity world as "superficial" and "self-involved." He confessed that he found it "difficult sometimes" to be a nice person in the midst of such superficiality.

Fast-forward to the present, and Gleeson has returned to the world of acting with renewed passion and purpose. His latest role in House of Guinness marks his most significant character transformation yet – from the sadistic Joffrey Baratheon to Byron Hughes, an ambitious and charming outsider.

When asked about his character, Gleeson revealed that he was drawn to Byron's complexity and vulnerability. "He is someone with a foot in both camps... He uses that to make himself valuable." This new role is a far cry from his GOT days, where he often played the villain. However, Gleeson seems to be embracing his inner actor once again.

The Netflix series, created by Peaky Blinders mastermind Steven Knight, promises to deliver a gripping tale of family, power, and betrayal in the world of brewing dynasties. With Gleeson at the forefront, it's clear that House of Guinness will be a wild ride.

Gleeson's personal life has also undergone significant changes since his GOT days. In 2022, he married his long-time girlfriend Róisín O'Mahony in County Kerry, and the couple seems to be enjoying a peaceful life away from the spotlight.

Despite his return to acting, Gleeson remains tight-lipped about his future plans. When asked about his goals, he jokingly replied, "When I'm destitute in 10 years' time, I'll accept any script!" However, it's clear that Jack Gleeson has finally found his footing in the world of entertainment.

As we reflect on Gleeson's journey, one thing becomes apparent – this actor is not just a talented performer but also a thoughtful and introspective individual. His decision to take a break from acting and explore other passions (he even started his own theatre company) speaks volumes about his dedication to his craft and his desire for authenticity.

House of Guinness is now available on Netflix, offering fans a chance to witness Gleeson's remarkable transformation and witness the birth of a new character. Will Byron Hughes become another iconic role in Gleeson's repertoire? Only time will tell, but one thing is certain – Jack Gleeson has arrived, and he's here to stay.
