There are several little allusions and Easter eggs relating to John Hammond (Richard Attenborough). Aside from the painting of him that Claire examines while waiting in Lockwood Manor, there's Lockwood's cane. At the top of the simple wooden aid, is the an amber with an ancient, fossilized mosquito housed inside it.
It becomes clear that these allusions weren't placed there just to excite old fans of the franchise; they speak to the state of Hammond's vision for these scientific breakthroughs. He was driven by ambition and a desire to evoke a sense of wonderment from the world, but just like the amber cane in the second act, that relatively innocent dream has been well and truly shattered by the greed of others.
It's really easy to miss this one, but the code to the elevator leading down to the facility beneath Lockwood Manor is 7337. Now, that might not mean anything to fans of the franchise, but it means something for director J.A Bayona, whose short film, 7337, gained him the attention of writer Sergio G. Sánchez and earned him the chance to direct The Orphanage. That film turned out to be Bayona's big break and now here he is, directing the latest entry in a famous and beloved framchise. All thanks to that short film.
We all remember how Jurassic World (directed by Colin Trevorrow) created an internet storm with Claire's choice of footwear when running through the jungles of Jurassic World. It was incredibly impractical. More so when we saw her running from a T-Rex with a flare and high heels. Credit to Bryce Dallas Howard for actually running in those heels, but to future filmmakers, it's probably best to spare a minute or two an have one of the principal characters abandon style when all hell breaks loose so they don't risk being eaten because of what we can only assume is an unshakeable stubbornness when it comes to fashion.
It's a lesson the filmmakers took to heart as we see in Fallen Kingdom when Claire hits the soil of Isla Nublar. The film makes it a point to show the audience that this time, Claire is equipped with slightly more appropriate gear and footwear more suitable for trekking through the mud and foliage of a tropical jungle.
Directed by J.A. Bayona and written by Colin Trevorrow and Derek Connolly, Jurassic World: Fallen Kingdom stars Chris Pratt, Bryce Dallas Howard and B.D. Wong, along with Toby Jones, Rafe Spall, Justice Smith, Daniella Pineda, Ted Levine, Geraldine Chaplin, James Cromwell and Jeff Goldblum. In theaters June 22.
