Was Squires missing, too?
When in doubt, blame the Rophorodo.
You picked some odd cast lists. I mean, Doctor Who, you don't watch, so you can be forgiven for picking ONE Doctor from ONE episode, but, Jenny Agutter for Red Dwarf? Really? I mean I remember Craig Ferguson guest starring as "Confidence," but I had to Google Agutter.
At least you picked the 1984 Dune, which may take a lot of liberties with the source material, but is inventive, entertaining and has a stellar cast. The 2021 version I walked out of when Duncan Idabro died 40 minutes late after slamming fast blades through the shield. If you're going to establish the SLOW blade penetrates the shield, then ignore your own established rules, I'm out. I'm too grumpy to deal with movies and shows which aren't more or less internally seif-consistent.
Also when in doubt, blame the Rophorodo. Unless it's a Walker clone, in which case I'm sure you can STILL blame the Rophorodo.
