Roger Dickens.Since we want to wander all over the map here, Here's a nice article about Roger Dickens and his involvement in Alien. I think it touches on salient points.
https://www.scified.com/news/roger-dicken-life-in-small-forms Did Dickens get enough credit? IDK. Did he demand it? IDK. I suspect for him, it was just another job. Hard to believe hanging out here, but Giger and Alien are not a religion for everyone. Some people have never even heard of him or seen any of the movies. I know that's not right, but it's true.
Both quotes are best taken in context. One is politically astute, the other is perhaps an expression of his deeper feelings on the matter. Contradiction? I'll go with Walt Whitman on that one.
The quote I referenced along with other info in Valaquen's article speak to my main point: Fair or not, Woodruff and Gillis got lumped in with the people "stealing Giger's art." From the interview with them, we know that was never the intention.
If Giger really wanted to be involved with A3 and have maximum input, he should have gone to London. I can also understand why he didn't do that. He talks about it in the Giger's Alien book, among other places. In a movie production, the hours are long, he hated the compromises, and so on. Even so, he was disappointed that Cameron did not invite him to participate in Aliens. Maybe by the time A3 rolled around, he didn't want the hassle. Hard to say and no one can ask him.
