The Koch brothers could easily finance a sweeping epic biopic about Reagan.
They would have to include the fact he was a democrat, divorced, headed a union, was for gun control, ran up a massive debt, etc. There is no way any kind of decent Reagan movie would further their cause in 2013. They would have to make it the Myth of Reagan a Fictional Tale. If they made it a propaganda piece it will be panned and flop. You can't make a profitable "epic" that you can only sell to American right wingers. So many movies depend of global box office receipts, DVD/Blu Ray sales, and pay per view to make their out sized returns. Creating a movie that from the beginning is going to have a tiny fraction of those things is not a wise financial move. I can't see the Koch brothers wasting money like that.
