Well, this is certainly going to make the NCIS and NCIS: Origins crossover even more special: Mark Harmon is reprising his role as Leroy Jethro Gibbs in the first hour.

CBS announced the news of Harmon’s special guest appearance on NCIS: Origins during the crossover on Tuesday, October 28. The event will be airing on Veterans Day, Tuesday, November 11, with Harmon appearing in the first hour (the shows swap time slots for the night). See Harmon as Gibbs again in the photo above.
