Alien - The Special Effects is almost solely about design and effects. Book Of Alien does have a lot of design and effects stuff too, but also talks about the setting and creature, and the genesis of the project. Not much about the cast and shooting. And since it was a studio publicity tie-in like Making of Alien Resurrection, you're not going to really get anything remotely controversial. The magazine had more on cast and characters, but again, no nitty gritty.
So while there would be a place in print for more on the actual shooting - between the official docos and Dennis Lowe's movies (ahem...) is there anything really left to tell?
