Dambusters Remake Filming?

Several months ago I read that there would be some filming in the UK at Scampton for the new “Dambusters” film and that this would take place in “April or May”. Has anyone heard or seen anything? I know the film is ostensibly being made “in secret” in NZ but it would be hard to film at Scampton without being in the public gaze. Has anyone heard anything about this?
