Baron Harkonnen is coming to Arrakis.

Stellan Skarsgard has joined the growing cast of Legendary Pictures’ adaptation of Dune, being directed by Denis Villeneuve.

Timothee Chalamet, Rebecca Ferguson and Dave Bautista have already been cast in the big-budget feature that is set for a spring production start and will shoot in Budapest and Jordan.

Skarsgard will play one of the villains of the piece, Baron Harkonnen, whose family previously ruled Arrakis and has a long hatred of the Atreides family, plotting with the galactic emperor to destroy it.

Chalamet has been cast as the lead, Paul Atreides, the son of the ruler of the family, who is forced to escape into the wasteland desert and partner with its nomadic tribes. Using his enhanced mental abilities, he eventually rises to become their ruler, with the nomads believing he is their messiah, and leads an army to overthrow the brutal empire.

Dune, considered a sci-fi literary classic, tells the multi-layered story of a fallen noble family’s attempt to control a desert planet named Arrakis and its export, a rare spice drug.

The script was written by Villeneuve, Eric Roth and Jon Spaihts. Villeneuve is also producing along with Mary Parent and Cale Boyter.

Skarsgard was most recently seen in Mamma Mia! Here We Go Again as well as in several recent Marvel Studios films as Erik Selvig.
