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.
10. Under The Silver Lake - The Hidden Message
Set in modern-day LA against a 50s film-noir aesthetic, David Robert Mitchell's polarising Under The Silver Lake follows Sam (Andrew Garfield) investigate the mysterious disappearance of his neighbour (Riley Keough), which involves strange symbols, hidden messages, a dog killer, and a nightmarish owl lady - yes, really.
Seeing as the film is all about hidden messages, it's only appropriate the film contains some of its own as Easter Eggs.
One of the most elaborate involves following a series of clues throughout the film, starting with a news message reading "Copiale graffiti". This refers to graffiti on a bathroom stall that uses the 250-year-old Copiale cipher. Cracking this reveals "coffee menu", which points to an earlier scene where Morse code is visible in a coffee shop. Solving that spells out another code that can be cracked using another hidden cipher, and if you manage that (with the help of another hidden clue) you'll have "What three words".
The aim now is to find these elusive words to get a location on website What3Words - although these are still up for debate. Some think it means using the Zodiac killer's cryptogram while others believe it's all just a wild goose chase.
