9. Jurassic ParkYear released: 1993 Overall U.S. box office gross: $357.1 million That's how big a beast that water-disturbing T-Rex was at the box office 20 years ago. It not only outgrossed latter-day summer superhero blockbusters such Spider-Man 3 ($336.5 million) without adjusting for inflation, but its freaky CGI velociraptors and dismembered Samuel L. Jackson inspired a 3-D run this year and a fourth installment to its film series next year. For some perspective that's 13 years after Jurassic Park III -- or an entire high-schooler's lifetime. If that doesn't make folks who saw the originals in theaters feel Jurassic, no amount of updated CGI will.
