THEN & NOW: The Cast Of 'Jurassic Park'

This weekend, Steven Spielberg's classic 1993 film "Jurassic Park" will return to theaters in 3D. 

It's been two decades since the dinosaur epic came to the big screen. 

We know Samuel L. Jackson went on to become a huge box-office success, but where did the rest of the cast land?

See what happened to Dr. Grant, leading lady Dr. Sattler, and the two children running around the dinosaur-infested park.

THEN: Actor Sam Neill helped lead an expedition into "Jurassic Park" as paleontologist Dr. Alan Grant.

NOW: Neill ditched dinosaurs for the law as a federal agent on short-lived "Alcatraz," and a police chief on upcoming BBC series "Peaky Blinders."

THEN: Laura Dern was grad student Dr. Ellie Sattler with a crush on Dr. Grant.
