Apparently, it involves a lot of jokes, at least according to Harington.
Yet whilst the Game of Thrones cast may all be in attendance, Kit has ruled out a themed wedding representing the HBO series. For the occasion, Leslie forced Harington to dress up in an awkward outfit.
Leslie, however, encouraged Harington to wear his Jon Snow costume.
Describing the moment he attended the party, Kit recalled: "It was really embarrassing". "The people bringing around canapés were looking at me thinking, 'You're sad man!" You've come dressed as your character.' I think the woman in the shop realised who I was as I was leaving.
The proposal didn't go exactly to plan as the famous actor got so excited that he asked Leslie too early. In it, the actress is seen opening the fridge and finding a fake severed head. "My family does April Fools". She didn't know what date it was, and after that she was in tears. "I did have some plans to do it, I was going to string up some lights in some trees and do all the romantic stuff but we were in the country and we were under this handsome night sky and had a log fire burning and red wine and I blew my load early".
The actor also recently revealed that he wants to move on to "more modern" roles as he prepares for the premiere of his new series about Guy Fawkes' infamous Gunpowder Plot. I think for the final season he is so stressed that he's reached that peaceful level.
