NCIS star Michael Weatherly revealed that it took several days for him to find out his sister died while he was filming. Weatherly, 57, who reprised his role as Tony DiNozzo in Paramount+'s spinoff NCIS: Tony & Ziva, recalled stepping away from acting after experiencing several personal losses. "I took a few years off because I had burned myself into a bit of a puddle. I was directing and acting, I did 125 episodes of Bull. I started seeing the writing on the wall, and I said, 'This is exhausting,'" he told Hello! Magazine on Wednesday, September 3.
