Rutger Hauer has signed on for True Blood Season 6.

The veteran movie star and Golden Globe winner will join the cast as a series regular, TV Line reports, coming on board as a sinister character named Macklyn. Look for him to have close ties to Sookie and Jason.

Season 5, of course, concluded with Bill going all Lilith on us and with the strong hint that the vampire Warlow would continue to haunt Anna Paquin's Sookie. Might Macklyn have some kind of connection to this mysterious blood sucker?

Hauer has guest-starred on episodes of Smallville and Alias, but this will mark his first steady television role.

True Blood kicks off a gory new season in June 2013.
