Bloody Disgusting reported today that casting has officially started for Jurassic Park 4. Laura Dern has been confirmed to return as Dr. Ellie Sattler while Sam Neill apparently is not that desperate enough for work. Giving audiences exactly what they want, in this installment the government has outfitted the pre-historic beasts with advance weaponry for battle purposes. Look for Jurassic Park 4 to hit the Wal-Mart $5 dollar bin sometime in the near future.
