Lincoln

Director: Steven Spielberg
 
IMDB: http://www.imdb.com/title/tt0443272

Review: Runs too long but otherwise sits as an impressive piece of work that manages to build cinematic tension despite prior historical knowledge.

Watch it if: You have some sort of interest in American political history.

And if you liked: A Man for All Seasons, Paths of Glory
