Steven Spielberg and DreamWork’s “Lincoln” is starting to look a larger ensemble piece by the day.

Tommy Lee Jones, Joseph Gordon-Levitt, Hal Holbrook, James Spader, John Hawkes, Tim Blake Nelson, Bruce McGill, Jeremy Strong and Joseph Cross have all joined the cast.

Jones will play Thaddeus Stevens, a Republican leader and powerful congressman from Pennsylvania in the U.S. House of Representatives. Stevens was a staunch supporter of abolishing slavery and was critical to writing the legislation that funded the American Civil War.

Levitt will play Lincoln’s eldest son, Robert Todd, who was Lincoln eldest son and Strong will play John George Nicolay who was Lincoln’s right hand man and private secretary all the way to his death.

Sources tell Variety that idea is to do something similar to “JFK” having a lot of big name stars included in the picture in almost cameo like appearances.

The pic has a passion project of Spielberg for sometime and will the cast now filling out it looks to be his next project. He is currently in post-production on “War Horse” which bows in December.

Touchstone is on to distribute with Tony Kushner adapting the script and Spielberg and Kathleen Kennedy producing.

Based on the novel “Team of Rivals” by Doris Kearns Goodwin, the pic is expected to focus on the political collision of Lincoln and the powerful men of his cabinet on the road to abolition and the end of the Civil War.

Lensing will begin this fall.
