User blog:Jhayk' Sulliy/Rick Carter Returns to JP4

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 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.
