As promised, Latino Review has revealed the identity behind the third actor reading for the part of Flash in three upcoming episodes of Arrow, which will debut during Season 2.

He is none other than Glee's own maniacal Sebastian Smith of the The Dalton Academy Warblers, Grant Gustin. So, to recap, here are the three top contenders to play DC Comics fan-favorite character Dr. Barry Allen.

Grant Gustin

Grant Gustin

"Grant Gustin is best known for his role in Glee as Sebastian Smythe of The Dalton Academy Warblers. Gustin won the recurring role of Sebastian, a promiscuous and scheming character, after "an exhaustive, weeks-long casting search". The 23 year old actor has indie Affluenza up next."

James Mackay

James Mackay

"Australian actor James Mackay, who will be seen in Roland Joffé's upcoming film Singularity, is the 2013 winner of the Heath Ledger Scholarship Award. The prize was awarded by Australians in Film, a Los Angeles-based nonprofit organization that serves as an industry guild for Australian filmmakers and performers in the U.S. The 28-year old actor has appeared in the Cry Havoc Theatre Company's contemporary adaptation of Julius Caesar and in such films as Don't Be Afraid of the Dark."

Matt Barr

Matt Barr

"Matt Barr is best known for his role as Johnse Hatfield in Hatfields & McCoys with Kevin Costner for the History Channel. The 29 year old actor was on the CW before in Hellcats playing series regular Dan Patch. Hellcats was canceled after one season."

The hope is to introduce Barry on Arrow, giving his origin story before spinning him off into his own series next fall. Shooting is scheduled to begin on September 30 for these Flash centric episodes. But he is not the only DC Comics character making their way to the small screen during Season 2.

Other DC Universe favorites making an appearance include Amanda Waller (Cynthia Addai-Robinson), The Black Canary (Caity Lotz), Bronze Tiger (Michael Jai White), and Sebastian Blood (Kevin Alejandro).
