Dune part 2 spoilers
I finally, belatedly saw Dune part 2. I didn't like it as well as the first part. I was a bit surprised that they decided to change it so that Alia wasn't born, implying the events of part 2 all took place in a matter of a few months, which is probably why they also wrote out Paul and Chani's first child. It seems like an unnecessary change. I'd say they probably did it for brevity, but those moves could not reasonably be called brief.

@sl38 Also, as one commentary I saw pointed out, arguably Walken has been training to be in Dune for years. 😄
