Arrow Heads to “Monument Point” As Episode 4.21 Starts Filming

Last week, filmmaker Kevin Smith started filming the twenty-first episode of The Flash‘s second season in Vancouver.

Last night, Arrow showrunner Marc Guggenheim revealed that their show was filming episode 21 as well, revealing the show’s title and creative staff.

Kevin Tancharoen, whose credits include an episode of Supergirl, two episodes of The Flash, and four of Marvel’s Agents of S.H.I.E.L.D., where his sister Maurissa serves as showrunner, will direct the episode from a screenplay by Speed Weed and Jenny Lynn. The title of the episode is “Monument Point.”

DC Comics fans may recognize “Monument Point” as the name of a fictional DC Comics city — one where the Justice Society of America used to operate. During the Brightest Day storyline, Monument Point was attacked by a being known as Scythe. Shortly thereafter, Doctor Chaos attacked it and killed the mayor. In both cases, the JSA stepped in to save the day, and at the end of it, The Flash (Jay Garrick) was named as temporary mayor.

Given the fact that Oliver Queen has been running for mayor all season long — and the fact that Doctor Chaos’s plot to bomb the city’s water supply feels distinctly like something they would do on Arrow, it seems like this might be a hint.

Arrow is back with new episodes starting this week.

The series airs at 8 p.m. ET/PT on Wednesdays on The CW.
