Mark Harmon Is Unrecognizable As Gibbs In NCIS & Origins Crossover Trailer

CBS has released the first trailer for NCIS and NCIS: Origins’ 2025 crossover, revealing an unrecognizable Mark Harmon as Leroy Jethro Gibbs. After some scheduling changes, the network dubbed NCIS’ block as “Super Tuesday”, returning the franchise to its original airing day. Jury is still out if it makes any difference when it comes to ratings, but it’s clear that CBS is determined to revive the franchise’s glory days.

Both NCIS season 23 and NCIS: Origins season 2 (and even NCIS: Sydney season 3) have come up with solid offerings since they debuted in the 2025-2026 network TV cycle. After a super-sized premiere for the flagship and Young Ducky’s return to the franchise, CBS is staging the shows’ first-ever crossover special. Per the official synopsis, Alden Parker’s MCRT comes across one of Gibbs’ earliest cases as part of the NIS, bridging the timeline gap.
