A Dr. Michael ‘Robby’ Robinavitch B Dr. John Carter C Dr. Mark Greene D Dr. James Wilson ✓ Correct! Dr. Carter and Dr. Greene are characters from ER (Carter was Wyle’s own iconic role), and Dr. Wilson is from House. Each of The Pitt’s 15 episodes covers exactly one hour of a single ER shift in real time, creating an unprecedented sense of urgency. Beyond the actual execution, what really makes Mark's death in ER stand out as the best of network TV after 24 years is that the show's creative team didn't rush to it.
