If you've been thinking that the cast of Steven Spielberg's Lincoln is big enough, you're dead wrong. Early last month it was reported that Tommy Lee Jones, Joseph Gordon-Levitt, Hal Holbrook, James Spader, John Hawkes, Tim Blake Nelson, Bruce McGill and Joseph Cross would be joining Daniel Day-Lewis and Sally Field in the presidential biopic, but apparently the great director is not done adding names that cause people to exclaim, "I love that guy!"

Coming Soon has learned that David Strathairn is the latest to join the extraordinary cast of Spielberg's next flick. In the movie, Strathairn will play William H. Seward, the man who served as Secretary of State under Lincoln. A strict opponent of slavery - in fact, it's widely believed that being so outspoken about the subject cost him a presidential nomination - Seward was a key member of Lincoln's cabinet during the years of the Civil War. The film is being based on the book "Team of Rivals" by Doris Kearns Goodwin, who adapted the book along with Tony Kushner. Strathairn has two film coming out later this year, including The Whistleblower with Rachel Weisz (which premiered at last year's Toronto Film Festival) and Maladies with James Franco. Lincoln is scheduled to be released in late 2012.

Seward is also on the record as being a badass survivor of an attempted assassination. On the same night that Lincoln was shot, Lewis Powell, an associate of John Wilkes Booth, broke into Seward's house and stabbed Seward multiple times in the face and neck. While the Secretary of State was left with a few scars, he lived for another seven years while Powell was captured the next day and killed. It's a true shame that probably won't make its way into the movie.
