There's been another "Swamp Thing" sighting, and it's even scarier one than the last.

DC released the latest teaser for its upcoming horror series on Monday, and it shows all kinds of nightmarish footage -- punctuated with screams, of course. While the previous teaser trailer focused on the titular monster (Derek Mears), we get to see more of the show's stars this time. The series' cast includes Crystal Reed, Henderson Wade, Jennifer Beals, and Andy Bean.

"Swamp Thing" is based on the DC comic books of the same name, which are created by Len Wein and Bernie Wrightson. The upcoming series centers on scientist Abby Arcane (Reed) as she investigates a deadly virus and instead discovers the horrors within a Louisiana swamp. See some of what's in store for her below, and be prepared to be creeped out.

"Swamp Thing" is set for 10 episodes and will premiere May 31 on the DC Universe subscription streaming service.
