In fact, if it weren’t for these comments from John Gajdecki, I don’t know I would have ever even have noticed a reliance on forested planets, but perhaps that’s simply a detail many of us never latched onto.
So, it seems eventually the VFX team found competent ways to create planets that featured much more than the forested landscape notable in the area.
At the end of the day, it’s good to know all of this factored into the creation of the well-liked sci-fi franchise, and its attention to detail is maybe one of the reasons it lasted as long as it did.
