I know it is a long shot but Hollywood hates Republicans. If RMB makes a convincing link between TSM and Corbutt which he already has, how much he hated Spanier which he does then the best movie would be a who dun-it....Joe or Corbutt. A dirty Republican Governor pulling strings in the background corrupting the AG and Judiciary to cover his a$$ with kick backs in the form of donations to get elected paints an interesting picture. Run that in parallel with whether there was a conspiracy by CSS and possibly Paterno that does not hold water and leave them guessing in the end would be a good movie.
Two potential villains and you figure it out in the end! I know I am dreaming but it would work.
Joe was a Republican, IIRC. You may need to re-work your plot.
