Bellisario retired in 2007, after widely reported tension with star Mark Harmon ended with the former's departure from "NCIS". Although he retains the title of executive producer, he has not had any real creative or executive involvement with "NCIS" since then. Bellisario later sued CBS over the creation of "", arguing his contract with the network entitled him to the first rights to create any "NCIS" spin off, as well as some share of profits from the new show. The suit was settled before trial in 2011 for an undisclosed amount. Bellisario's production company was named "Belisarius Productions" after the Roman general Belisarius, of which "Bellisario" is an Italian-language variant.
