Rumors no more

The Johanna casting rumors are rumors no more. Jena Malone has officially been cast as Johanna Mason. Both IMDb and Flixter have her listed as Johanna. Also noteworthy, Lenny Kravitz for the first time has been lock in, along with Willow Shields and Donald Sutherland, although my assumption was from the beginning that all three would appear in all three (or four) films. (In case you were unaware Mockingjay is being split into two movies. My hope is that this casting will be promptly followed up by Finnick and the rest of the tributes. Actually the whole rest of the cast, and movie would he nice too. Anyways, your ideas, who should play Finnick, Beetee, Wiress, and Mags? Thanks!
