We all love watching movies. The thrill, the drama, the romance—put ’em all together and you’ve got entertainment for hours on end. Every so often, though, writers and directors throw in an interesting detail or two that most viewers overlook. The term for these hidden secrets is Easter Egg, meaning a hidden reference placed in movies, video games, and television series. They can be there as a way to show appreciation, provide a laugh, or reveal something deeper.
The practice is similar to Alfred Hitchcock’s cameo appearances in all of his movies, although Easter eggs usually aren’t as obvious. It sometimes takes a die-hard fan to catch them—do you have what it takes?
 I Am Legend
During the Times Square hunting sequence in I Am Legend, Will Smith passes a billboard advertising a Batman and Superman team up all set to release in 2010. Given the 2007 release, had the hidden message come true, the film would have likely featured Brandon Routh and Christian Bale. Even though it took Warner Bros a few more years to pit together the two superheroes, their Man of Steel sequel of Batman Vs Superman starring Henry Cavill and Ben Affleck is on its way, and we can’t wait to check it out.
