Despite the fact that several of the fantasy series' characters collaborated to kill Snow - played by Kit Harington - it was Olly who finished off the Lord Commander of the Night’s Watch.

When the season 5 finale - Mother's Mercy - was aired last year, fans went into overdrive as they watched Olly stab Snow, seemingly ending his life.

Some viewers couldn't accept Snow was dead, with others blaming O'Connor personally for the twist in the plot.

Speaking to the Brighton Argus, the 16-year-old actor said: "It's laughable how people think the show is realistic enough for them to send messages like this to someone who is not the character. I find it quite funny."
