Hard Times - S1-E3
Trivia: Budget limitations means the original plan for the Globe scene to feature a packed theatre had to be cut down, because they couldn't afford hundreds of extras with full costume starting at 5am, in order to finish before the theatre was used for a performance later in the day. Unwilling to cut the scene entirely, Neil Gaiman realised if they altered the sequence such that Hamlet was a flop, they could get away with just a few extras and work that into the dialogue.
Trivia: The show is based on a comic books series written by Gerard Way, who was the lead singer for the band My Chemical Romance.
