Critics have praised Shannon’s portrayal for turning a relatively forgotten leader into a figure of powerful emotional weight.
Matthew Macfadyen as Charles J. Guiteau
Matthew Macfadyen portrays Charles J. Guiteau, Garfield’s assassin. His performance captures Guiteau’s erratic behavior, delusions of grandeur, and tragic descent into madness.

Bradley Whitford as James G. Blaine
Bradley Whitford plays James G. Blaine, a prominent political ally of Garfield and one of the era’s most ambitious power players.

Shea Whigham as Roscoe Conkling
