You might have been too preoccupied to notice on Sunday evening, but the Season 6 finale of The Walking Dead was directed by executive producer and special effects master Greg Nicotero.
As many Walking Dead fans will know, Nicotero likes to include special Easter Eggs or references to the masters of the horror genre in episodes he directs. When Nicotero directed Episode 12 we got a tribute to the 1981 film Ghost Story, but this week we got a slightly different type of tribute.
Remember when Morgan and Carol took refuge in the library that was formerly used by a group of survivors that the Saviors had killed?
Well, if you looked carefully you would have noticed that the library was named the Viskocil Public Library.
Seems like kind of a unique name, right? Well, it turns out it was a reference to Academy Award-winning special effects guru Joe Viskocil.
Even if you don't immediately recognize Viskocil's name, you'll certainly be familiar with his work. Over the years, Joe Viskocil worked on over 80 films, including Terminator 2: Judgement Day, Independence Day (for which he won his Academy Award for Best Visual Effects), Star Wars: Episode IV and Star Wars: Episode V, Godzilla and many, many more.
Perhaps Viskocil's most famous piece of visual effects work was in Star Wars: Episode IV - A New Hope when he created the blast that enable Luke Skywalker to destroy the Death Star. He also brought the giant AT-AT walkers to life on the ice planet Hoth in Star Wars: Episode V - The Empire Strikes Back.
As is often the case with Greg Nicotero's tributes, he and Viskocil had worked together on Leatherface: Texas Chainsaw Massacre III back in 1990.
Sadly, Viskocil died in 2014 at the age of 61, making this small tribute in The Walking Dead a very nice tip of the cap to a true master of special effects.
'The Walking Dead' will return with Season 7 in October, but 'Fear The Walking Dead' returns with Season 2 next Sunday, April 10 on AMC.
