The two leading ladies are part of a busy day of pilot casting buzz.
According to The Hollywood Reporter, Maestro will join LL Cool J and Melinda Clarke in CBS' "The Man," playing a doctor with close ties to the show's central undercover cop.
Maestro played Nadia on ABC's "Alias" and has also appeared in the features "Poseidon" and "Secuestro Express."
Lucio, best known as Lindsay from "The O.C.," has taken one of the leads in CBS' very "Angel"-esque drama about a vampire (Alex O'Laughlin) who works as a private investigator. Lucio will play a TV reporter in the pilot.
Also at CBS, Hector Elizondo will play the family patriarch in the untitled drama from Cynthia Cidre. Formerly titled "Los Duques," the show focuses on a multi-generational Latin American family in the rum business and also stars Jimmy Smits, Nestor Carbonell and Rita Moreno.
Elizondo has an upcoming role on ABC's "Grey's Anatomy" and has a long list of feature credits including "The Flamingo Kid," "Pretty Woman" and the upcoming "Georgia Rule."
In other casting news, Stephen Moyer is set for the lead in FOX's drama "NSA Innocent." The series focuses on an ordinary guy enlisted to spy on a defense contractor. Moyer's credits include the upcoming feature "88 Minutes" and the USA miniseries "Starter Wife."
