‘Manhattan’

A new episode called “Damnatio Memoriae” opens Season 2 of this critically acclaimed but under-watched historical drama, which producers reveal will be about how its core characters react as they draw closer to the July 1945 test launch and the bomb assumes more of a real-world aspect instead of being just numbers on a chalkboard. New series regulars Griffin Dunne and Mamie Gummer join returning actors John Benjamin Hickey, Olivia Williams, Rachel Brosnahan and Christopher Denham.
