Devin Faraci at CHUD [3] is reporting two more names for Spielberg’s (apparent next film) The Trial of the Chicago 7:
Colin Hanks (as Rennie Davis) and Jeff Daniels (as Dave Dellinger)
Vanity Fair [4] already mentioned Sacha Baron Cohen (as Abbie Hoffman) and Philip Seymour Hoffman (as William Kunstler) along with the possibilities of Will Smith, Taye Diggs, Adam Arkin, and Kevin Spacey.
Aaron Sorkin apparently turned in a screenplay before the writers strike deadline.
