That said, fans of the first Jurassic Park will find this latest installment stuffed to overflowing with references and callbacks: Park founder John Hammond (played by Richard Attenborough in the

holographic display; and the boys stumble into the ruined lobby of the original park, where they find a tooth of that very first T. rex.
