NCIS season 21 has been put on hold due to the ongoing SAG-AFTRA strikes, leaving fans waiting to see what happens next. However, two NCIS actors, Brian Dietzen and Katrina Law, have shown their support for the strikes by joining the picket line together. They shared photos on social media, receiving encouragement from fans. This is not the first time the NCIS cast has voiced their support for the strikes. It is unclear when the show will return, but it may not be until autumn 2024.
