His performance as Joe Gargery in Great Expectations at the Gate Theatre, Dublin was described by Irish Independent critic Bruce Arnold: "Emphasis on the heart-warming relationship between Pip and Joe Gargery is a crucial part of the story, and the blacksmith, played by Murray McArthur in the best performance of the evening, achieves this".
