Donald Sutherland has been selected to be President Snow. This is an important character selection since President Snow is the person responsible for the continuance of the Hunger Games in Panem and the one who keeps control over the districts through his consolidated power in the Capital:
In Collins’ novel, President Snow is described as “cruel and ruthless in his intimidation and control tactics,” ruling over Panem and its contained districts for 25-plus years. He and District 12 tribute Katniss (Lawrence) have a contentious relationship throughout the series. (source)
The good thing is that Sutherland looks like President Snow’s description in the books. And Sutherland has played bad guys before which is a plus. Looking forward to this movie next year.
