Not too long ago, Gary Glasber, Mark Harmon, and Jeffrey Lieber, the executive producers of 'NCIS: New Orleans', shared a few plot details at the TCA Summer Press Tour. They disclosed that Gibbs will be appearing in one episode of the show, resulting in a crossover between the two series.

The show creators have also planned episodes involving Michael Weatherley and Pauley Perrette. David McCalum will also be making an appearance in one episode. Rumors say that FBI Agent Fornell, portrayed by Joe Spano, will also make an appearance in New Orleans.

Apart from these crossovers, the new show will also have several new actors playing new characters. For instance, Scott Bakula will be portraying the character of Dwayne Cassius Pride, the NCIS Agent who is in charge of the entire New Orleans crew.
