'Jurassic Park' was certainly a dinosaur-sized hit when it came out in 1993.

The Steven Spielberg-directed thriller became the highest grossing film up to that time, going on to haul in close to $1 billion worldwide and setting the stage for a few sequels, with the fourth installment due to come out next June.

While the movie's selling points were more its spectacular special effects and exciting plot, 'Jurassic Park' did feature a pretty strong cast. See what the stars of 'Jurassic Park' are up to these days below.
