This article mostly contains quotes, from Natalie about Eve, that we’ve already seen. However, there is one new detail of interest:

Portman said an alternative ending had been shot with Bacall, adding: “I loved both of them.”

She said it was “fantastic” to be able to have a choice.

Hard to speculate since we don’t even know what the current ending is, but it also nice to have options. Smart move on Natalie’s part.
