Warning: Spoilers about "Game of Thrones" season 4 are ahead.
With its many battles, trials by combat, and all out wars, season four of HBO's "Game of Thrones" was one of the most visually spectacular shows on television this past season — all thanks to the series' amazing visual and special effects.
Some of these effects especially stand out, like those featured in the attack on The Wall in the ninth episode "The Watchers on the Wall." However, a season 4 VFX reel by one of the series' visual effects artist Calvin Romeyn, which has since been made private, shows that some of these effects were a bit harder to see.
For example, those flaming arrows shot back and forth between the Night's Watch and The Wildlings during the attack were digitally added.
Another minor effect you may have not noticed was how the missing fingers of Davos Seaworth (Liam Cunningham) weren't missing at all.
Using green covers on each finger and standing in front of a blue screen allowed Cunningham to be in the Iron Bank of Braavos with four less digits.
Visual effects also played a big part in many major moments of the season.
Effects helped render the dying, poisoned face of King Joffery in episode two, "The Lion and the Rose."
Digital rendering also helped to make Prince Oberyn's head smash look even more gruesome in the trial by combat from episode eight ("The Mountain and the Viper").
Finally, one of the most shocking moments from the season — when Petyr "Littlefinger" Baelish pushes his new bride Lysa Arryn to her death in episode seven ("Mockingbird") —was done thanks in part to special effects and a green screen positioned within the set.
