Also known as in-jokes, Easter eggs in movies can often be as hard to find as the chocolate variety post-Easter. Here are five obscure examples that continue to delight eagle-eyed movie buffs…

PREDATOR 2
An Alien skull in the Predator’s trophy case was a cool touch that not only winked at Fox’s other sci-fi franchise, it led to two Alien vs. Predator spin-off films! Moreover in Predators (2010), an Alien skull can be spotted on the ground of a campsite.

GREMLINS
A pair of Spielberg in-jokes makes an appearance as Billy Peltzer strolls past the local cinema. The films ‘A Boy’s Life’ and ‘Watch the Skies’ are in fact the working titles for E.T. The Extra-Terrestrial and Close Encounters of the Third Kind, respectively.

I AM LEGEND
A prescient bit of advertising appears in the 2007 film when Will Smith enters the ruins of Times Square – a billboard promoting Batman vs. Superman. Does this mean the plague broke out in 2016? Not exactly – I Am Legend writer-producer Akiva Goldsman was working on an early BvS script draft at the time.

THE MIST
Just prior to the mist rolling in, Thomas Jane’s character is in his studio painting what Stephen King fans will immediately recognise as Roland the Gunslinger from The Dark Tower novels. The painting is actually the work of artist Drew Struzan.

THE HILLS HAVE EYES and THE EVIL DEAD
In Wes Craven’s original horror classic, a poster of Jaws is torn in half during the trailer attack sequence. As a subtle homage, Sam Raimi included a ripped poster of The Hills Have Eyes in the basement of the cabin in The Evil Dead.
