Death by Lightning 

Short, tight and terrific recounting of the 1880 presidential election of James Garfield and his subsequent assassination by Charles Guiteau. A really tremendous cast of Michael Shannon as Garfield and Nick Offerman as Chester A Arthur really brings home this script, but the tour de force is Matt MacFadyen (Succession) as the sycophantic Guiteau that will have people talking. He plays pretty much the same bootlicker as his character on Succession but he does it so well and it fits in here like a glove. Don't Hesitate.
