After Kensi Blye’s brief visit to Oahu in episode 2.06, it’s great to hear that CBS has big repeat crossover plans for Hawaii Five-0 and NCIS: LA in May!
A case involving a lethal virus will bring Special Agents Callen (Chris O’Donnell) and Hanna (LL Cool J) to Honolulu in an episode of Five-0 and McGarrett and Danny will follow up with a visit to California on NCIS: LA. The episodes will air on consecutive nights.
William Keck at TV Guide has the details:
“It was great fun earlier this season to see Danni soaking up the sun on Hawaii Five-0, so when CBS asked if we were interested in doing a double episode crossover, we jumped at the idea,” says Shane Brennan, the mastermind behind both NCIS series. “What we’ve come up with is an enormously entertaining, high octane story that showcases the very best of both shows. It’s going to be a fun ride.”
Adds Five-0 showrunner Peter Lenkov, “Besides the obvious excitement of teaming up with an incredible show, expanding Hawaii Five-0‘s universe [and] teaming with NCIS: LA on a case with huge stakes, we’re interested in exploring the relationship between McGarrett and Hanna, both SEALs with a little history.”

Thank you Mizz. I just heard the great news that H50 and NCIS: LA will have a double cross in May 2012. That is just awesome. Good luck and best wishes to H50 and NCIS: LA during May sweep month.
