How Aiden Gillen went from a schemer to a rogue

He’s best known as the master string-puller in Game of Thrones, but Aidan Gillen plays a likeable ex-con in his new film, writes Ed Power

I had fretted about this moment. Gillen, after all, has a reputation for not suffering idiots. At our last meeting, during a day promoting RTÉ’s Charlie Haughey biopic (Gillen played the opinion-splitting politician) he had been conspicuously on edge, grumpy even.
