In coordination with the release of Hyde Park on the Hudson and Lincoln this fall, Slate broke down the history of presidents in movies, starting with Washington (70 appearances) up to Obama (21 appearances).
1. Lincoln (the Clint Howard of presidents, with 130 appearances)
2. Washington (70)
3. Grant (47, mostly in Westerns)
4. Jefferson (46)
5 (tie). Nixon and George W. Bush (36)
And that doesn’t even include Bush’s decapitated appearance in Game of Thrones.
