As the show is set to lean heavily on Alan Moore's '80s-era handling of the Swamp Thing title, it will most likely portray Woodrue as a scientist tasked by the military with the mission of finding out how Alec Holland became the marshy monster in the first place.
He comes to discover that the beast is not Holland, but a sentient plant being that merely has possession of Holland's body and memories, causing it to believe that it is Holland. Woodrue eventually gains the ability to control plant life via a special chemical formula, goes insane, and tries to exterminate all life on Earth, but is thwarted by Swamp Thing.
In a storyline by Neil Gaiman, it is revealed that Woodrue was the college botany professor of Alec Holland and Pamela Isley, responsible for transforming the latter into Poison Ivy. In 1997's infamous Batman & Robin (directed by Joel Schumacher), Dr. Woodrue (played by John Glover) creates both Ivy (Uma Thurman) and Bane (Jeep Swenson).
Last week, it was announced that Andy Bean (It: Chapter Two) and Derek Mears (Friday the 13th) would play Holland and Swamp Thing respectively. With much of the ancillary casting already out of the way, Durand's participation seems to indicate that the series is just about ready to enter production.
Durand's other genre screen credits include X-Men Origins: Wolverine, Legion, Real Steel, Resident Evil: Retribution, and Noah.
