Noah Wyle and Sally Field first worked together on “ER,” when Wyle was among that show’s breakout stars and Field was already an established legend. Now, they’re reuniting to discuss emotionally charged work they’ve done in the past season. On “The Pitt,” for which Wyle won the Emmy for best actor in a drama last season, protagonist Dr. “Robby” Robinavitch had a seasonlong existential crisis, culminating in his admitting to thinking about suicide. In the TV movie “Remarkably Bright Creatures,” Field’s Tova, an aquarium janitor who is herself grieving, finds a new lease on life thanks to her bond with an octopus called Marcellus.
