One of the many, many reasons we love watching movies is that they always have so much more to offer with each new viewing. Whether that be a seemingly throw-away line that foreshadows things to come, details in a shot you never noticed before, or the finer details in the film-making itself, there's always a reason to watch something again.
Likewise, plenty of filmmakers will often fill their films with sneaky hidden details or references known as Easter Eggs for eagle-eyed film nerds to spot for some lighthearted fun.
Some Easter Eggs are pretty well known. It's likely you'll already be familiar with Toy Story including the carpet from The Shining's Overlook Hotel, the Pulp Fiction reference on Nick Fury's tombstone in Captain America: Winter Soldier, or Alfred Hitchcock's many cameos in his own films.
However, there are some Easter Eggs out there that are so well hidden it's likely they went straight over your heard the first or second (or even third) time you've watched the film.
Finding these Easter Eggs would have taken some serious detective work by dedicated viewers spending no shortage of hours pouring over every frame to unearth these hidden details you never noticed.
