Giancarlo Giuseppe Alessandro Esposito was born in Copenhagen, the son of Giovanni “John” C. Esposito, an Italian stagehand and carpenter from Naples, and Elizabeth “Leesa” Foster, an African-American opera and nightclub singer from Alabama.
When Esposito was six, his family moved from Copenhagen to Manhattan. He attended Elizabeth Seton College in New York and earned a two-year degree in radio and television communications.
Esposito made his Broadway debut in 1968, playing an enslaved child opposite Shirley Jones in the short-lived musical Maggie Flynn (1968), set during the New York Draft Riots of 1863. He was also a member of the youthful cast of the Stephen Sondheim-Harold Prince collaboration Merrily We Roll Along, which closed with 16 performances and 56 previews in 1981.
During the 1980s, Esposito appeared in films such as Maximum Overdrive, King of New York, and Trading Places. He also performed in TV shows such as Miami Vice and Spenser: For Hire. He played J. C. Pierce, a cadet in the 1981 movie Taps.
In 1988 he landed his breakout role as the leader (“Dean Big Brother Almighty”) of the black fraternity “Gamma Phi Gamma” in director Spike Lee’s film School Daze, exploring color relations at black colleges. Over the next four years, Esposito and Lee collaborated on three other movies: Do the Right Thing, Mo’ Better Blues, and Malcolm X. During the 1990s Esposito appeared in the acclaimed indie films Night on Earth, Fresh and Smoke, as well as its sequel Blue in the Face. He also appeared in the mainstream films Harley Davidson and the Marlboro Man with Mickey Rourke, Reckless with Mia Farrow, and Waiting to Exhale starring Whitney Houston and Angela Bassett. In 1995 Esposito was featured in a music video “California” by French superstar Mylene Farmer, directed by Abel Ferrara.
Esposito played FBI agent Mike Giardello on the TV crime drama Homicide: Life on the Street. That role drew from both his African American and Italian ancestry. He played this character during the show’s seventh and final season, and reprised the role for its 2000 made-for-TV movie. Mike’s estranged father, shift lieutenant Al Giardello, is portrayed as subject to racism, something Esposito’s character practiced in School Daze. Another multiracial role was as Sergeant Paul Gigante in the television comedy, Bakersfield P.D.
In 1997 Esposito played the film roles of Darryl in Trouble on the Corner and Charlie Dunt in Nothing to Lose. Other TV credits include NYPD Blue, Law & Order, The Practice, New York Undercover, and Fallen Angels: Fearless.
Esposito has portrayed drug dealers (Fresh, Breaking Bad, King of New York, Better Call Saul), policemen (The Usual Suspects, Derailed), political radicals (Bob Roberts, Do the Right Thing), and a demonic version of the Greek God of Sleep Hypnos from another dimension (Monkeybone). In 2001, he played Cassius Marcellus Clay, Sr. in Ali, and Miguel Algarín, friend and collaborator of Nuyorican poet Miguel Piñero, in Piñero.
In 2002 Esposito was cast as a legal eagle in the David E. Kelley television drama Girls Club. Although the series only lasted one season, and did not garner generally positive reviews, it represented a personal turning point for Esposito, who related to The Washington Post, “I started to play bosses. And I realized, ‘Oh, okay, this is an opportunity.’ It was really a great opening for me to show who I really was. And it’s kept going like that.”
In 2005 Esposito played an unsympathetic detective named Esposito in the film Hate Crime, which centers upon homophobia as a theme.
In 2006 Esposito starred in Last Holiday as Senator Dillings, alongside Queen Latifah and Timothy Hutton. Esposito played Robert Fuentes, a Miami businessman with shady connections, on the UPN television series South Beach. He appeared in New Amsterdam and CSI: Miami. In Feel the Noise (2007), he played ex-musician Roberto, the Puerto Rican father of Omarion Grandberry’s character, aspiring rap star “Rob”.
From 2009 to 2011, Esposito appeared in seasons 2 through 4 of the AMC drama Breaking Bad, as Gus Fring, the head of a New Mexico-based methamphetamine drug ring. In the fourth season, he was the show’s primary antagonist, and won critical acclaim for this role. He won the Best Supporting Actor in a Drama award at the 2012 Critics’ Choice Television Awards and was nominated for an Outstanding Supporting Actor in a Drama Series award at the 2012 Primetime Emmy Awards, but lost to co-star Aaron Paul.
Esposito appeared in the first season of the ABC program Once Upon a Time, which debuted in October 2011. He portrayed the split role of Sidney, a reporter for The Daily Mirror in the town of Storybrooke, Maine, who is the Magic Mirror, possessed by The Evil Queen in a parallel fairy tale world.
