I think Peeta and Gale weren't cast right, either. I do think Peeta should've been young, as he was, but in the books he was one of the townfolk and was fed better than the likes of Katniss and Gale. Gale was supposed to be a bit older, but he still looked like a teenager too.
Even Katniss and Gale weren't as bad off as most, since they were able to hunt, so I can understand their characters being a bit plumper than others. But it all just looked too pretty for me to believe it. I don't really think they could've successfully portrayed Katniss as starving and still appeased all the fangirls who wanted to see a beautiful heroine and her equally beautiful love interests.
