I’m not sure when this was announced, but: Austin Butler is playing Feyd Rautha in Dune 2.
This is a pretty key role, and much was made of the fact that there was no casting news about it for the first installment, largely because there was no need to show him in the first half of the story, I reckon. Feyd is the nephew to the Harkonnen duke and primary antagonist, and is positioned in the narrative as a sort of anti-Paul. In the 1984 film, Sting played him as if there were no such thing as overacting. (Not for nothing, Butler is the same age now that Sting was in 1984, which is in line with the rest of the primary cast choices I mentioned here last year.)
Given Butler’s recent fame from the titular role in Baz Lurman’s Elvis, it’s easy to imagine the sort of nutbird mashups we’re likely to get, and for once I’m here for it.
