"Swamp Thing" has added two actors, including one who will play the show's titular monster.

"Power" star Andy Bean and Derek Mears ("Friday the 13th") have joined the DC Universe series, Deadline reports. Bean will play a biologist, while Mears takes on the role of the so-called swamp thing. The upcoming show is already set to star Crystal Reed.

"Swamp Thing" follows Abby Arcane (Reed) as she tries to uncover the danger a Louisiana swamp holds. Although a virus is originally thought to be the culprit, there's actually something even more terrifying. Meanwhile, biologist Alec Holland (Bean) is also working in the swamp when he becomes transformed into the Swamp Monster (Mears). The cast also includes Maria Sten, Jennifer Beals, Jeryl Prescott, Virginia Madsen, and Will Patton.

The upcoming show is based on the comic books of the same name created by Len Wein and Bernie Wrightson, which also inspired the 1982 film "Swamp Thing."
