Murphy was four days into filming his scenes for the upcoming season of HBO's hit fantasy series "Game of Thrones," when he passed away.
The Belfast-born actor, was cast to play the role of Ser Denys Mallister, the oldest member of the Night’s Watch, in the fifth season of the adaptation of George RR Martin’s Song of Ice and Fire series. He reportedly collapsed and died on Friday, 8 August, having shot only a few scenes in the role.
According to his agent Phillip Young, Murphy was “absolutely delighted”, to be cast “in one of the biggest productions in the world at this stage in his career.”
According to The Arts Council of Northern Ireland, Murphy served as a mentor to many young actors in the region, including Liam Neeson.
Game of Thrones producers David Benioff and D.B. Weiss released a statement regarding the actor's passing on Monday. "We will not be recasting J.J. Murphy," they told Us Weekly. "He was a lovely man, and the best Denys Mallister we could have hoped for. And now his watch is ended."
Having been working in the Northern Irish theatre scene from the late 1940s, Murphy was an active member of Equity, the British actors’ union, and had worked for years at Belfast’s Lyric Theatre. His death, says Young, is a “tragic loss” and comes at the end of a “long and full career”.
