Where can Jurassic Park go after becoming the highest-grossing film of all time ($912.3 million worldwide)? If you were anywhere near a video store last week, you know the answer. The dinosaur adventure debuted at No.1 on both the sales and the rentals charts, with the biggest initial shipment of a movie ever (22 million copies, says an industry source). A $24.98 price tag with tie-in rebates totaling $22.50 and a huge ad campaign created a Jurassic frenzy well ahead of its Oct. 4 sale date. T. rex and Co. will need that bite to fend off the hugely anticipated Snow White and the Seven Dwarfs, due in stores Oct. 28.
