Alexander Skarsgard aka Eric Northman on True Blood [as Finnick]!
Too old. I could actually see him as a young President Snow, although of course it would be better if they could get Donald Sutherland's actual son to do that. (Also, word to the person who looks forward to seeing more Sutherand as Snow. That scene where he comes to visit Katniss before the victory tour is really chilling, and I know he'll play it quiet and sinister.) I’ve read Taylor Kitsch is a favorite, and I would be THRILLED if Tim Riggins were in this series. And he did play a teenager for a long time, but he looks his age (30) now. Armie Hammer has been thrown around a lot and he IS in his mid-20s, but he looks 30ish to me. I’ve also read that Zach Efron would be a good choice and he’s age-appropriate and attractive, but can he act? (I’m seriously asking; I’ve never seen any of his movies.) I also wonder if they'd want to cast someone who's a bigger name than Lawrence.
Of the suggestions floating around, Kristen Bell is a big fat no in my book, but I do like the idea of Naya Rivera.
Ditto – I think Kristen Bell is exactly the wrong choice. She doesn’t have the viciousness needed to play Johanna; she’s tiny and cute and not at all vicious-looking. Snark and viciousness aren't the same. Naya Rivera would be much better – she regularly plays vicious on Glee.
I can't remember how Johanna was described physically, but I think I pictured her dark. (I pictured Finnick as this guy B. I went to college with - tall, tan, sandy hair, muscular, rowed crew ... just a total J.Crew-model-esque WASP like Armie Hammer played the Winklevoss twins.)
Movie Clove definitely didn't look 17/18 either.
Clove was 14 in the book and the actress who played her is 15 (was 14 during filming, born in February 1997).
Mila Kunis could be good- I could buy her as someone that could fake out people into thinking she's a weakling, and at the same time turn around and axe them in the back.
Funnily enough, I pictured Katniss as a taller Mila Kunis – she has the olive skin, light eyes, and dark hair the way Katniss is described.
