I woke up this morning (okay, it was 11am, so not really morning...) and checked my facebook and lookie what I saw!!
OMG! Finnick!!!!!! I could not be more excited for Sam as Finnick. He says in the article that they did indeed do the sugar cube scene and that he was in a fishnet. *fans self* can't wait. Now to stalk my mailman until he brings me my copy of this so it can go on my wall. If you don't have a EW subscription, you really should get one. It's only like, $25 a year and you get a copy each week. It's awesome.
Here is the article: Look, it's Finnick!
Here is another picture from Catching Fire that I found on Entertainment Weekly's fb page.
