In the teaser, about halfway through, was an image of a skinny, pale woman with a mass of tangled, strawberry-blonde hair on her head. Immediately, we thought it could be Suicide Squad member and Batman villain Harley Quinn.
A great many of our readers thought the same.
Comicbook.com reached out to Arrow Executive Producer Marc Guggenheim about the buzz online, told him that our readers were really excited by the prospect that Harley Quinn was shown in the trailer for the "Suicide Squad," and included a link to our previous, speculative story on the matter.
This tickles me no end. I'll tell you two things:
1) this is NOT the special announcement -- that's episode 219 and this is 216 2) to paraphrase Aaron Sorkin: "There's gonna be an episode of Arrow. I'd watch."
The second point, it's worth noting, is a reference to "Two Cathedrals," an episode of The West Wing. The second season finale, which dealt with the President's hidden Multiple Sclerosis and the death of a beloved supporting character, it's one of the most acclaimed single episodes of TV of all time.
During his Inside the Actors Studio episode, series star Martin Sheen was told by host James Lipton that this was "one of the best episodes in the history of American television."
So, all in all, not a bad reference to drop.
Arrow returns on March 19 with "Suicide Squad." I guess we'll know for sure by then.
