Chris O'Donnell's Surprise Move to '9-1-1: Nashville'

Chris O'Donnell is now portraying firehouse chief Captain Don Hart in the ABC procedural drama "9-1-1: Nashville." This role follows his extensive tenure as Special Agent G. Callen on "NCIS: Los Angeles," a role he played from 2009 until its conclusion in 2023. O'Donnell's career began with guest spots in the 1980s before he transitioned to feature films.

His filmography includes notable roles such as Charlie Simms in "Scent of a Woman," for which he received a Golden Globe nomination, and D'Artagnan in "The Three Musketeers." He also famously donned the cape as Robin in "Batman Forever" and "Batman & Robin" in the mid-1990s. O'Donnell later made a significant return to television with arcs on "Grey's Anatomy" and the miniseries "The Company."

O'Donnell initially did not plan to immediately join another network procedural after "NCIS: Los Angeles." However, he was approached by Ryan Murphy for the "9-1-1" spin-off set in Nashville. He mentioned that "9-1-1: Lone Star" alum Rob Lowe was instrumental in persuading him to take on the new gig, describing the move to Nashville as a surprisingly appealing opportunity.
