Noah Wyle "became" his character from The Pitt and treated an injured co-star on set.
The 54-year-old actor leads the cast of the real-time medical drama as Dr. Michael 'Robby' Robinavitch and he sprang into action when Laetitia Hollard accidentally banged her elbow while shooting in the crowded "control hub" of the main set, leading to a bloody scrape.
