Who's Playing Finnick Odair?

So I just finished reading the rest of The Hunger Games trilogy (Catching Fire and Mockingjay), and seemingly, one of the most compelling characters in the second book of the highly successful The Hunger Games Series is the tribute from District 4, Finnick Odair. I feel that this character would be the most anticipated character on next year's release of the film sequel. True enough, when I searched the net about the possible candidates – many actors were already being considered by the fans of the book to play the coveted role (though there is no confirmation yet from Lionsgate)

Who is Finnick Odair?

Finnick Odair was a male victor from District 4. He was known for being the victor of the 65th Hunger Games and a survivor of the 3rd Quarter Quell, also known as the 75th Hunger Games.

Physical appearance

Physically, he is described as being extremely handsome. He is tall, muscular, and athletic, with tan skin, bronze-colored hair, and "incredible" sea-green eyes, making him very popular with people in the Capitol.

Katniss says that Finnick never needed to do anything for sponsors and that no other tribute could overcome his "natural beauty." – The Hunger Games Wikia

And as a fan myself, here are the actors whom I visualize playing the role.

ALEX PETTYFER from I Am Number 4, Beastly, In Time, and the upcoming film Magic Mike.

CHACE CRAWFORD from Gossip Girl

CAM GIGANDET from Twilight, Burlesque

And the relatively known Australian actor LACHLAN BUCHANAN whose features alone looked very promising for the role!

So who do you think should play Finnick Odair?
