Jonathan Pryce has given an interview about his work on Game of Thrones for the Polish website Kawerna and he allowed himself to reveal a bit than he probably should in one of the answers. We hid the spoiler behind a break further below.
In the rest of the interview, he provides his view on the character of High Sparrow: as goes for many characters on the show, he believes that his cause is just and his deeds are good. He also draws parallels with the (historical) character of Cardinal Wolsey, whom he played last year on Wolf Hall. Lastly, Pryce admits that the most miserable part of the job is that he needs to keep going around barefoot, even in wide shots – though there is always someone around with a hot water bottle to help out between the takes.

OK, SEASON SIX SPOILERS, AVERT YOUR EYES.
Pryce says he looked through the season six scripts when he got them to see what happens to his character and found a scene that was just unbelievable. Later he quite openly describes the (setup of a) scene from a future episode concerning Cersei’s trial. It is going to take place at the Great Sept and practically everyone is said to be present there. The High Sparrow has grown over-confident and believes that Cersei simply has to show up, even though he gets informed she has not left her chambers. At the same time, there is a great deal of scheming taking place behind his back, in the immediate vicinity. The Sept slowly fills with people and the High Sparrow is still pleased with the situation, with everything apparently going according to the plans – little does he know that fate has an unpleasant surprise in store for him.
An additional spoilery bit comes our way courtesy of Hull Daily Mail, via commenter James Rivers (thanks). A piece on the local hero Rob Aramayo playing young Ned Stark reveals that we will see him briefly again in expisode six before “a significant showing in episode ten”. This cannot mean anything else but that they are saving the grand Tower of Joy reveal for the season finale. Cannot wait!
