Mark Harmon might be ready to hang up retirement for good. Sources tell the National Enquirer that the NCIS favourite has rekindled his passion for acting after a recent guest appearance on the show.
The 74-year-old, who left the series four years ago, reprised his iconic role as Leroy Jethro Gibbs during the first-ever NCIS and NCIS: Origins crossover on 11 November.
