Eugene Simon has been with Game of Thrones since Season One. As Lancel Lannister, we saw him as Cersei's cousin-turned-lover who then joined the Faith Militant. He's stayed tight-lipped for six seasons about the notoriously secretive HBO show, but now that Lancel has met his fiery end, Simon is dishing on what happened behind-the-scenes. Here are 10 things that we didn't see in the finale:
1. The actors have known for a year what happened in the finale. And the only thing that bound them to keep it a secret was "word of honor."
I found out a year ago. I've known for a year. There's no contract signed to make sure you don't say anything. There's not much of any warning, really, just not to post anything of you filming on set on social media. It's actually just a word of honor for each one of the actors, which is a rather nice culture of the Game of Thrones cast. The actors have honed their ability to be able to do it.
2. A lot of people guessed how it ended.
You'd be surprised how many people made educated guess that there was Wildfire underneath the Sept of Baelor. A lot of people put the pieces together. I would say, Huh, interesting, and leave it at that.
3. That Wildfire was really glowing green.
That chemical has a slightly glowing property to it. I think it's the same chemical they use on stop signs so you can see them at night. The camera showed you the same glowing effect that you saw in real life.
4. They recycled the location for the tunnels under the Sept of Baelor.
It was filmed at a castle just outside of Belfast, which has an intricate amount of catacombs underground. We've been using that set for many occasions. It's not the first time I've filmed there.
5. If the Wildfire doesn't get you, the spiders and bats will.
It's an incredibly long corridor that goes on for 200 or 300 meters. It takes a long time to find your way down there. There are very large spiders and there a huge number of bats that live down there. If you go down to the end of that tunnel and shine a light, you'll see dozens and dozens of bats looking back at you.
6. They used real fire for the explosion.
When we were trying to film the actual explosion itself, we had a pyrotechnics team put in front of me to get the first glimmers, to capture the first moments when the fire touches the Wildfire. That sequence of events—catching the reflection in Lansel's eye—took a very, very long time. I was incredibly close to live fire. It was about a foot away from my face.
7. You couldn't actually see the fire reflection in Simon's eyes, though.
It was done with CGI, mostly. At the last minute, there was CGI done with the reflection of my eyes.
8. The child actor who stabs Lancel found the whole thing hilarious.
The young man who stabbed Lancel in the back and paralyzes him was an absolute sweetheart and a nice kid with a great sense of humor. He was very adult for his age. He found it hilariously funny that he was going to be the one to stab Lancel in the back and run away.
9. One of Simon's final scenes was cut.
When he stabs Lancel in the back, there was a bit cut from that scene. To make sure Lancel has been paralyzed, he very slowly puts the knife into Lancel's left leg and Lancel doesn't respond, which means that he can't feel anything and that was proof that Lancel couldn't move.
10. Simon's got a very interesting theory about who will end up on the Iron Throne.
I think it'll be either Jon Snow or Tyrion. Nothing against Daenerys, she's a wonderful character, but I have a feeling she may be in trouble next season. It's just a feeling—it's no hint at all!
