Alfred Molina has signed to star on Law & Order: Los Angeles as Deputy District Attorney Morales, a show rep says.

The 57-year-old actor joins previously announced star Skeet Ulrich on the upcoming spin-off, set to debut this fall on NBC.

"I am thrilled that Fred is 'LOLA''s Deputy D.A.," creator and executive producer Dick Wolf said in a statement to Deadline, which first reported the news. "He joins a remarkable list of some of America's greatest character actors like Sam Waterson, Vincent D'Onofrio, Jeff Goldblum, Steven Hill, Dianne Wiest  and Michael Moriarity as stars of the Law & Order-branded series."

Morales is described as a narcissistic but self-deprecating and altruistic prosecutor, according to casting breakdowns. Coming from a political family, he hopes to serve in public office one day.
