Stellan Skarsgård has joined director Denis Villeneuve's new Dune adaptation, strengthening what was already a quickly growing and impressive cast. Skarsgård is probably best known for his role in as Professor Erik Selvig in the Thor films.

Now, it has been announced that he'll portray Baron Vladimir Harkonnen in Legendary Entertainment’s adaptation of the classic Frank Herbert novel.

The villainous Baron Harkonnen is an antagonist to the story's lead character, Paul Atreides, and is featured throughout not only the original Dune, but several of Herbert's other related novels as well.

The role of the Baron has been played by two actors previously. First by Kenneth McMillan in David Lynch's 1984 film Dune, and then by Ian McNeice in 2000 for the Syfy miniseries Frank Herbert's Dune. McNeice returned for a sequel series -- Frank Herbert's Children of Dune -- in 2003 to reprise the role.
