Ballincollig native Aidan O’Callaghan is set to play Kareg in the four-episode spin-off. The 34-year-old made his first on-screen debut in 2014 in KILL DAY, a post-apocalyptic TV series set in 2050’s Britain. But Aidan has been well acclaimed for his role in the English TV show EASTENDERS, where he played the antagonistic barman, Lewis Butler earlier this year.
