There was another well known Hollywood actor who was in line for the role of Gibbs.
According to the X-Ray feature on Amazon’s Prime Video, Indiana Jones actor Harrison Ford could have been the star of NCIS.
The feature reads: “Harrison Ford, who was experiencing a bit of a slump around the time of the series’s conception, was urged by colleagues to pursue the role of Gibbs.
“He did not, but Mark Harmon’s Gibbs does allude to this in the first episode, name-dropping Harrison Ford and his film Air Force One (1997).”
NCIS is available to watch on CBS.
