  • Actor bio

Bill Nunn stars as no-nonsense EMT, Vietnam vet and Twix aficionado “Cassius ‘Cash’ Clay” on USA Network’s hit comedy series SIRENS. 

Nunn has left an indelible mark on the world of film and television since his career began in the 1980s, deftly navigating drama and comedy while maintaining his commitment to teaching and mentoring younger actors. He has served as artist-in-residence at Spelman College and for the Georgia Council of the Arts while tackling challenging and diverse roles on the stage and on screens both large and small. 

A native of Pittsburgh, Pennsylvania, Nunn graduated from Morehouse College in Atlanta, Georgia. His fellow alumni include Spike Lee, who would direct Nunn in his feature debut, School Daze and in one of his most memorable performances as Radio Raheem, whose omnipresent boombox is at the heart of the action in the Academy Award-nominated Do the Right Thing. Other film credits include Touchstone Picture’s Sister Act, Incorporated Television Company’s The Last Seduction, Touchstone Picture’s He Got Game and the Columbia Pictures Corporation Spiderman trilogy from director Sam Raimi. 

Nunn starred in numerous television movies and scored his first regular series role in 1994 with CBS’s Traps, playing Jack Cloud in the police procedural. His next major television role, ABC’s The Job, marked his first collaboration with SIRENS Executive Producer Denis Leary, who created and starred in the detective drama and took an instant liking to Nunn. This budding relationship led Denis to cast him in his Comedy Central Christmas Special before making him a SIRENS series regular. Nunn has guest starred in multiple shows, including Bakersfield P.D., Chicago Hope and October Road. 

Nunn appeared as Bobo in the 2004 Broadway revival of Lorraine Hansberry’s A Raisin in the Sun, alongside music mogul Sean “Diddy” Combs in his stage debut.  Nunn reprised the role in a 2008 TV movie, the television premiere of the classic play. That same year he took to the stage again for the Kennedy Center’s “August Wilson’s 20th Century,” commemorating playwright August Wilson, whose 10 plays, collectively known as The Pittsburgh Cycle, document the African-American experience in the 20th century.
