I'm kinda' getting irritated at this whole "let's cast 1 person a day" thing. They casted Stanley Tucci as Ceasar (in my brain he was Bob Barker- even though Bob is super old his skin is always tan, he always look part shark...). But the movie is out in a little over 10 months. This sucker should be casted, filming, and ready instead of this... Studios lately are deciding to do these tent poles at such weird times waiting to the last minute in some cases; compared to years ago where they did a tent pole in 2-3 years and the actors would be like "Oh I filmed that when I first met my (signficant other), and now we're married with a kid on the way..." on the DVD extras.
Cast Haymitch, Cinna, Snow, right now (today!) then start filming, find 16ish random school aged kids and ask "want to be in a movie?" and there you have all the tributes that battle it out except the big ones... We don't see the others really so make a kids life and go to a skate park at 3pm. There casting is done.
