Actress Bridget Moynahan, known for her role as Erin Reagan on the TV show "Blue Bloods," recently spoke about the challenges of shooting night scenes. In an interview with TV Insider, Moynahan revealed that filming at night is difficult for her because she is an early bird who goes to bed at 9:30. As an advocate for a healthy lifestyle, Moynahan believes in maintaining a regular sleep schedule. However, as an integral part of the show, she has had to film many scenes at night due to her character's role as an assistant district attorney.
