Animal House was pretty accurate......
More seriously, Roberto Rosellini made a number of movies which strove for historical accuracy rather than box-office appeal, such as La Prise du Pouvoir par Louis XIV (The Taking of Power by Louis XIV), which showed how Louis XIV made himself the real master of the French government instead of a figurehead. He also did a movie on the Renaissance and one on the Age of St. Augustine.
Agreed. Animal House. Good times.
