"Arrow" executive producer Marc Guggenheim spoke about the announced "The Flash" television drama in the CW's "Arrow" universe, and the challenge of expanding the DC Television Universe in a way that doesn't sacrifice the unique tone of "Arrow."
"I think a lot of people are justified in asking 'What does this mean for Arrow in terms of its tone?' And my answer is that the trick that we have -- and this is a challenge we've discusses a lot and have an awareness of how to face it head on -- is the fact that 'Arrow' is like 'Iron Man' where 'The Flash' will be 'The Hulk,'" said Guggenheim. "And just as 'The Hulk' coming out did not change the tone of the Iron Man movies, 'The Flash' will not change the tone of 'Arrow.' We're very cognizant of what 'Arrow' is all about, and I think the Marvel movies demonstrate that each piece of a universe can have its own feel. 'Thor' is consistent with the tone of Thor while 'Captain America' is consistent with the tone of Captain America's character. 'Arrow's' tone will remain consistent much in the same way, and we are looking forward to expanding our canvass a bit. And judging from the announcement, I think the fans are looking forward to it as well."
