On Monday of this week, Latino-Review.com reported on three actors that were being considered for the role of Barry Allen, aka The Flash, for The CW’s Arrow. One of the names mentioned was Grant Gustin from Glee and according to TV Guide, Gustin has been picked for the role.
Barry Allen will premiere in episode 8 of Arrow and again in the 9th episode in the upcoming season. Then once more time in the 20th episode which will be the back door pilot to a potential Flash series. So looks like we have our Flash. Not quite sure how I feel about the choice, seems a bit too young for the character to me, but will have to wait and see the first couple of episodes he’s in. (Source: TV Guide)
