Gains No. 1 slot for year after 10 days

It was boffo, it was bronto, it was $ 38,455,860 for the second weekend of Universal’s “Jurassic Park.”

Superlatives were the order of the day as Steven Spielberg’s dino-mighty picture leaped past the $ 100 million barrier in record speed and simultaneously became the top grossing film of 1993.

“Jurassic” averaged $ 15,780 for the frame, head and shoulders ahead of any other wide release.

And considering the second weekends for many past cash cows, “Jurassic’s” 23% fall has to be considered almost trivial.

Last week Universal said it believed the pic could clear $ 200 million within a month. (That would make it several days faster than the reigning champ “Batman Returns.”) Now, it looks possible for the film to reach that level in as little as 23 days.

It is a box office phenomenon so huge it’s impossible to keep up with the momentum.

But events of the past weekend — namely, the opening of Columbia’s “Last Action Hero”– were scheduled to slow that momentum. This was to be the weekend battle of the giants, the dinosaurs vs. the biggest movie star in the world in a duel to the death. Or, at least, a race where the winner would be decided by crossing the $ 200 million finish line.

Instead, Col’s “Hero” wound up its debut weekend with $ 15,338,241, a significant notch beneath the studio’s once-buoyant expectations. The action-fantasy registered mild averages of $ 6,651.

Many of the town’s movers and shakers were having more fun focusing on the performance of the Arnold Schwarzenegger vehicle than on the behemoth known as “Jurassic Park.”

Officially, Columbia is saying it was pleased by the film’s performance, but, off the record, few have been buying that line.

People want to know the worst-case scenario.

Columbia’s marketing prexy Sid Ganis says it is possible that “Last Action Hero” could follow in the footsteps of “Twins,””Hook” or “Honey, I Shrunk the Kids” and hold its ground for an eventual gross of more than $ 100 million.

There are, of course, other possibilities. For instance, the film might mirror such titles as “RoboCop 2” or “Alien3” with a strong opening and a fast fade to $ 45 million-$ 55 million.
