Throughout Game of Thrones' eight-season run there were plenty of sex scenes, but one, in particular, had an unforeseen complication. According to George R.R. Martin, the sex scene in the pilot was ruined by a horse.

Martin explained what happened to EW, saying, "There are a couple of stories. As a wedding gift, Khal Drogo gives Daenerys a silver horse and she rides away. For a moment you think she’s fleeing. Then she turns the horse around and leaps the horse over a big campfire. Drogo is very impressed, and it starts the relationship on a good note. We tried to film this scene. We got a top stunt rider and a top horse, a silver filly, but the filly would not jump that campfire. She got close and then was like, 'There’s fire there!' and would turn the other way. We tried to film it a half dozen ways. So [director Tom McCarthy] goes, 'Put out the fire and we’ll do the fire with CGI.' They put out the fire and the horse would still not jump the dead fire. It’s a smart horse. It knows it’s not burning now, but it was burning a little while ago! So they had to scrap that sequence, which was unfortunate, as it was a bonding moment between Dany and Khal Drogo."

He continued, "Then came the filming of the wedding night. In the Emilia Clarke version, it’s rape. It’s not rape in my book, and it’s not rape in the scene as we filmed it with Tamzin Merchant. It’s a seduction. Dany and Drogo don’t have the same language. Dany is a little scared but also a little excited, and Drogo is being more considerate. The only words he knows are 'yes' or 'no.' Originally it was a fairly faithful version."

He elaborated, "So we’re by this little brook. They tied the horses to the trees and there’s a seduction scene by the stream. Jason Momoa and Tamzin are naked and 'having sex.' And suddenly the video guy starts to laugh. The silver filly was not a filly at all. It was a colt. And it was getting visibly excited by watching these two humans. There’s this horse in the background with this enormous horse schlong. So that didn’t go well either."
