Arrow and The Flash Won't Tie Into Constantine

In a new interview with Green Arrow TV, Arrow executive producer Marc Guggenheim seems to have confirmed that Constantine will not take place in the same shared universe as Arrow and The Flash.

When reviewers who have seen the Constantine pilot took note of a wink-and-a-nod reference to Ivy University during the show, some fans started to wonder whether Arrow and The Flash would tie into that NBC series.

Constantine, also based on a DC Comics property but airing on NBC, seemed the least likely of all the various DC properties to tie into the Arrowverse. Up to this point, though, Gotham's producers had denied any involvement with the CW series and The CW confirmed that iZombie would not share the superheroes' universe. It was only Constantine left to the imagination of fans -- and given the overt DC Comics references in the trailer, it got people talking.

But yesterday at the Television Critics Association, not long after Geoff Johns confirmed that DC's movies and its TV properties will not share a universe, Guggenheim said that for the time being, the only thing sharing a universe with Arrow and The Flash are...Arrow and The Flash.

While Ray Palmer -- recently cast on Arrow and a professor at Ivy University in the comics -- might still have a connection to that institution (GATV got a "keep watching"-type of answer there), any connection he might have to it wouldn't connect to the Ivy University in Constantine, Guggenheim said.

"When we do our Easter eggs, they're never in conjunction with other DC Easter eggs," he said, adding that Arrow is "just in the Flash universe."
