New York stage actor Colin Donnell will round out the cast of Arrow, playing Tommy Merlyn in The CW pilot based on DC Comics' Green Arrow, Deadline reports.
He joins Stephen Amell, Katie Cassidy, David Ramsey, Susanna Thompson and Willa Holland in the “very provocative and sophisticated and edgy” superhero drama from Green Lantern screenwriters Greg Berlanti and Marc Guggenheim and Fringe co-executive producer Andrew Kreisberg.
Hung alum Amell stars as Oliver Queen, a wealthy young bad boy who, after spending five years shipwrecked on an island, returns to Star City with a mastery of the bow and a determination to make a difference.
Donnell, who made his TV series debut on ABC's Pan Am, will play Oliver's best friend, described in a leaked character breakdown as "a spectacularly rich young man whose life revolves around parties, clubs, liquor and lots of anonymous sex. Unlike Oliver, he can’t seem to understand his former best friend’s sudden change of lifestyle and direction."
The character is a nod to the DC Comics villain Merlyn, an archer introduced in the early 1970s as a rival to Green Arrow. It's probably a safe bet we'll eventually see Tommy pick up the bow to oppose his best friend, should The CW move ahead with Arrow.
