Who should play Flash?

With all the talk about the Flash cameo in Arrow Season 2, who should play Flash. This cameo will lead into his own series, which should lead into his own movie. What I am hoping for is, if Flash goes from tv to movie, then Arrow will do the same. I'm not saying lets make an Arrow movie, but atleast to have Stephen Amell to be in Justice League, just someone give that man a goatee please.

From everything I've read, Flash will be in his red suit, called Flash. Everything looks like it will be pretty much straight forward about Flash. So the question still stands who should play Flash.

Here are my Top 3.
1. Bradley Cooper (highly unlikely due to it be a tv show)
2. Charlie Hunnam
3. Arron Paul. ( why not, he could be Barry Allen, since Breaking Bad is done)
Honorable Mention to Liam Helmsworth.... I've seen some people bring his name up, that would just be funny, one brother is Flash and one is Thor haha

Honestly.. I really think Ryan Reynolds would be a good fit.. To bad hes already Green Lantern. The movie wasnt that good... I can just see him fit the role for Flash.

I also think Vin Diesel would to. (lolol umad Greg) XD

Try looking up Scott Speedman. He has the look and I saw him in Last Resort. I thought he did a good job on that. And since that just go canceled he should be available. (also his name is Speedman, it fits)

Neil Patrick Harris.  

i'll take your Neil Patrick Harris, and top you with Jim Parsons

I thought about that, only I'm not sure if he could do it seriously.  Or maybe I would just always see him as the Flash from Big Bang mentally.

I want an unknown for this part. I think with all the pressure that will come from a part like this bringing in someone ready and willing to prove themselves with that role could be a good thing for the part and the character.

Agreed, but also for the fact that an unknown might be more apt to 'stick with it' longer than an established actor.

It's amazing that Robert Downey Junior has stuck with Tony Stark as long as he has, though I imagine his gazillion dollars probably lets him adapt to it better than most.

But I just find it so irritating to have an actor introduce a character I love from books/comics only to leave after a couple of instances to find themselves or something.
