"Since 2003 [Ledford’s] been shopping the idea of making a live-action version of Neon Genesis Evangelion, […] Ledford signed on the Weta Companies, […] to come up with plans for what the Evangelion world might look like. But instead of micromanaging the project, Ledford had Weta answer to two Evangelion fanatics at his company."
Through badgering and extensive communication with Weta it shows that ADV are taking this film very seriously. This isn’t going to be a cheap knock off; ADV simply cannot afford to offend the great majority of their customers. And to that means it seems they want to do things right, with or without Hideaki Anno.
"Richard Taylor, Weta's co-founder, says he's never experienced anything quite like it. Twice a week he'd have a conference call with the fans at ADV, sending them renderings of his designs for things like the 100-foot-tall robots and getting in return their encyclopedic take on the interpretations. "These are people who could be considered scholars on the world of Evangelion," says Taylor. "We had to appease them and find their approval."
It follows on to mention a meeting between Taylor and a proposed producer at the San Diego Comic-Con in an attempt to ‘jump-start’ the production. Budgeting is also mentioned and it seems ADV has raised $100m of the $120 million they need.
