They fail to mention that actor Dave Bautista also co-stars in the new DUNE 2021.
From what I can google, he plays Glossu "Beast" Rabban. The oldest nephew of The Baron Harkonnen (arch-enemy of The Duke Atreides & House Atreides).
A particularly nasty bad guy/character. Should be fun.

Comment: The 1984 version of DUNE actually deleted a few characters from the book.
Hopefully this new version of DUNE, being a two-parter, will use the expanded format to restore a few of the lost characters for a more accurate rendition of the original book.
