The actor who plays Aemon Targaryen of the Night’s Watch is actually blind in real life.

Joffrey Lannister is based off of Roman ruler Caligula.

Sophie Turner (Sansa Stark) actually adopted the dog who was killed by the Lannisters in season one.

Emilia Clarke (Daenaerys Targaryen) got stuck to a toilet seat because so much fake blood had dried on her body and it adhered to the porcelain.

The horse heart that Dany eats in season one was made out of gummy bears, which explains how she got stuck to that toilet seat.

Any noble-born bastards are given surnames based on where they were born. The Reach - Flowers, the Westerlands - Hill, the Iron Islands - Pyke, the Riverlands - Rivers, in Dorne - Sand, in the North - Snow, the Vale - Stone, the Stormlands - Storm, the Crownlands - Waters.

One of the melted swords in the Iron Throne is actually Gandalf’s sword from the Lord of the Rings trilogy.

The entire series is based off of the characters and stories that George R.R. Martin came up with while playing with his pet turtles. Seriously. He even claims his house’s sigil is the turtle.
