It's not a movie, but I do have an idea for a future Jurassic project. My Idea is a Jurassic Park prequel TV series. It would be animated, but made for a somewhat more mature audience. It would focus on Hammond and the creation of Jurassic Park, showing certain events that lead up to the first film, such as Nedry being hired and what lead to him betraying InGen to help Biosyn, The big one taking over the raptor pack, and the incident that lead to the raptors having to be held in the holding pens. It would also develop certain plot points that were briefly mentioned in the films (to help tie the Park and World trilogies together), such as exploring the partnership with Hammond and Benjamin Lockwood (eventually showing how the human cloning concept lead to the falling out between them), giving more backstory to Charlotte Lockwood's work with InGen, and showing the labs on Sorna before they were abandoned.
