When deciding what the greatest blockbuster of the 1990s was there isn't much competition against Steven Spielberg's incredible Jurassic Park. Titanic might have ended up beating it in the box office receipts department but Cameron's film just can't hold a candle to Spielberg's dinosaur romp. Whether or not the upcoming Jurassic World will come close to the greatness of the original remains to be seen - the trailer has left many divided, concerned that it might go down a more far-fetched avenue than it really should - but it's got a high standard to match whichever way you look at it. The sequels that followed never quite reached the same levels of goodness, although the second instalment, Jurassic Park: The Lost World certainly came the closest. But there is still pleasure to be had in rewatching even the sequels. While the franchise might not be anywhere near as easter egg heavy as, say, the Marvel cinematic universe or the Pixar movies, eagle-eyed viewers will spot a few treasures here and there if they look close enough. Here are fifteen Jurassic Park easter eggs you probably never noticed.
