Yes, that's right, Jurassic Park 4 has gotten a second art directer, and someone who is familiar with the series. Rick Carter, who worked on the art direction for Jurassic Park (1993) and The Lost World: Jurassic Park (1997), but was dropped for Jurassic Park /// (2001) in favor of Ed Verreaux, However, it appears that Carter is teaming up with Verreaux to help dead the art production for Jurassic Park 4!
Personally, I think Universal wants to get things done as best they can, and hope that bringing in a veteran to the franchise would help Verreaux understand exactly what they're looking for. And I am glad to hear a good, experienced crew is being put on to complete this. This is exactly what JP4 needs to be successful.
