NCIS Los Angeles is set to end this weekend, and it is expected to leave viewers emotional. The series finale will focus on the team investigating stolen military-grade weapons, but it is the personal plot involving Agent Callen and Anna Kolcheck's wedding that will tug at heartstrings. The images released ahead of the finale show the couple opting for a simple and intimate wedding. Chris O'Donnell, who plays Callen, revealed that he took some mementos from the set, including his chair, bulletproof vest, badge, and boots. O'Donnell also expressed admiration for his character's constant search for truth and answers. NCIS Los Angeles is the second NCIS franchise to be cancelled, following NCIS New Orleans in 2021. However, the franchise is still going strong with NCIS and NCIS Hawaii being renewed for future seasons.
