Leonardo Nam has been cast as Harlan Edwards in DC Universe's upcoming Swamp Thing television series, according to Deadline. The character is described as a "gay CDC specialist who is Abby's (Crystal Reed) second-in-command."
Harlan Edwards is apparently a new character created for the show, as there's no significant character with that name in DC Comics lore.
Nam is best known for his role as Felix Lutz in HBO's Westworld, but DC-CW fans might remember him as Melting Point from CW's The Flash.
Filming on Swamp Thing is underway now, with the series anticipated to debut in May 2019 on the DC Universe streaming service.
