This isn't James' first time appearing in the NCIS franchise, as he previously played the role of Lieutenant Commander Gregory Pullman in season 16 of the original show back in 2019. He also portrayed Delta Unit Leader in season six of NCIS: LA - which has recently been canceled.
James marked his appearance on the show on Instagram, sharing some behind-the-scenes snaps of him and Vanessa on set. "Hey gang tune into to NCIS: Hawaii tonight and catch a glimpse of my old mug!!" he wrote in the caption. "Got to work with one of my dear friends @vanessalachey in paradise. Thanks V for the opportunity, I’m so grateful for this. You and everyone with the show went above and beyond to make me feel welcome.
