Troian Bellisario talks playing a police officer in ‘On Call’, reflects on ‘Pretty Little Liars’ 15th anniversary

In On Call, Troian Bellisario plays Tracy Harmon, a veteran field training officer in the Long Beach Police Department, navigating the mental and physical toll of her job while mentoring rookie officer Alex Diaz (Brandon Larracuente). The role marks a striking shift from her Pretty Little Liars days, and Bellisario admits she was surprised when first approached to play a police officer.

“Tracy Harmon, veteran police officer, 40 years old. I thought, ‘Oh my god, I’m never going to get this,’” she admits.
