10 Best Movies Starring Game Of Thrones Actors

4. Aidan Gillen - Calvary

If Jon Snow was once known by some fans of Game Of Thrones as the most boring character on the show, the award for most annoying is likely to go to Petyr Baelish, played by Aidan Gillen. To be fair, Gillen's performance can come across as annoying for a reason - Littlefinger is an snake-like manipulator who shouldn't be trusted.

Taking on the atheist doctor Frank Harte in Calvary sees the Irish actor notching thinks up a few gears, trading the soft-whispering mind games with a nihilistic, cruel energy as he challenges Father James (Brendan Gleeson) over his crisis of faith. As renowned a presence on stage as he is in front of the camera, Gillen is perhaps best known and admired for his award-winning performance as politician-on-the-rise Tommy Carcetti in another excellent HBO series, The Wire.
