The ensemble for the upcoming 'NCIS: New York' spinoff continues to take shape with the addition of four new series regulars.

LL Cool J is set to reprise his role as NCIS Special Agent Sam Hanna, the legendary agent returning to his New York City roots to lead operations at the field office. Scott Caan joins him as NCIS Special Agent Nick Schaeffer, a roguish partner tasked with helping manage a fresh team handling high-stakes missions to protect one of the world's most critical cities and ports.

Jennifer Beals has been cast as Assistant Special Agent in Charge Robyn Wells, the head of the NCIS New York field office who relies on her instincts and commands respect from her team. Beals' television and film background includes appearances in 'Luckiest Girl Alive,' 'Devil in a Blue Dress,' 'The L Word,' and 'Book of Boba Fett.'

Jacqueline Byers will play NCIS Special Agent Addison "Addy" Ross, described as a tough and resourceful agent with something to prove. Byers has previously appeared on 'Salvation,' 'Dark Winds,' and 'Roadies,' along with films including 'Forbidden Fruits,' 'Ice Fall,' and 'Shadow of God.'

Shane Harper rounds out the new additions as NCIS Special Agent Wyatt Hill, a fearless and sharp operative who excels in fieldwork. Harper recently appeared in 'Power Book IV: Force' and previously worked on shows including 'Good Luck Charlie,' 'Hightown,' 'A Teacher,' 'Awkward,' and 'Happyland.'

Devin Druid completes the quartet as NCIS Tech Specialist Sean Sullivan, a witty and brilliant technician who questions authority. This marks Druid's return to television in a series regular capacity for the first time in six years, following his work on Netflix's '13 Reasons Why,' as well as prior appearances in 'Olive Kitteridge' and 'Louie.'

The series will debut on CBS this fall.
