"Emerald Archer" is the twelfth episode of the seventh season of Arrow, and the one-hundred-fiftieth episode overall. It aired on February 4, 2019.
The 150th episode of Arrow showcases a documentary entitled "The Hood and the Rise of Vigilantism" starring Oliver Queen, Felicity Smoak and the rest of Team Arrow. As a camera crew follows Oliver and team around to talk about their past as vigilantes and what the Green Arrow means to Star City, Oliver must also deal with William's return from boarding school as well as a new threat to the city. The episode will feature "documentary footage" captured by the BTS crew and interviews from those who have worked alongside the Green Arrow. The documentary is narrated by Kelsey Grammer.[src]
Stephen Amell previously teased the episode having a mockumentary feel that appeared in several shows like The Office.
The clapper contains two easter eggs. Marcia Pedowitz's surname pays homage to The CW president Mark Pedowitz while the photographer references J.D. Davison who worked as an A-camera operator for "Pilot" and this episode.
