Why, yes, that is Matt Ryan as John Constantine.
The reels kicked off this afternoon's giant-size "Warner Bros. Television Takeover" presentation, featuring The CW's "Legends of Tomorrow," Fox's "Gotham," CBS's "Supergirl" and "Person of Interest," and NBC's "Blindspot."
Watch the highlight reels below, then stick around for CC Jitters' new drink "The Flash": one shot of espresso in drip coffee. It's a thing, Ollie. Really.
"The Flash" airs Tuesdays at 8 p.m. ET/PT on The CW, followed by "Arrow" on Wednesdays at 8 pm.
