Cast and Characters (Training Day) Training Day

Detective Alonzo Harris — Denzel Washington

A thirteen-year veteran LAPD narcotics detective who has crossed so far over the line that the line is no longer visible. Alonzo is charming, erudite, brutal, and desperate -- he owes the Russian mafia $4 million by midnight and has engineered an entire day of criminal activity to pay it. Washington plays him as a man who long ago convinced himself that his corruption was competence.

"I've done 30 pictures, and this is the first time I've played a truly evil character. It's not for want of trying. It's just that no one has ever asked me to play a bad guy before." — Denzel Washington, FandomWire (2002)

Washington unlocked the character through a single phrase he wrote on his script: "The wages of sin are death." He later explained what that meant for his approach:

"Once I put that down on the page, I felt that I could be as wicked as I wanted to be because I knew what was coming." — Denzel Washington, SlashFilm (2021)

Washington described Alonzo as "an arrogant thief, liar, killer, and egomaniac" and explained the character's desperate logic: "On the day we meet him, he sees two options in his life. One is death, and the other is what he sets out to accomplish. That gave me the license to be as evil as possible." The performance earned Washington the Academy Award for Best Actor -- the first African American to win the award in the leading category since Sidney Poitier in 1964. The American Film Institute later ranked Alonzo Harris as the 50th greatest screen villain of all time. (wikipedia, imdb)

Officer Jake Hoyt — Ethan Hawke

A young patrol officer trying to move into plainclothes narcotics work, Jake spends the film's single day being tested, corrupted, threatened, and nearly killed -- and refusing, at the final moment, to break. Hawke plays Jake as genuinely decent but not naive; he knows the streets are rough, but he hasn't imagined how deep the rot goes.

"He's an amazingly confident man. He knows who he is, and he fills the room, and he knows what he wants, and he expects a lot from other people." — Ethan Hawke on Denzel Washington, The Ringer (2018)

Hawke earned a Best Supporting Actor nomination for the role. Years later, he reflected on losing the Oscar with characteristic generosity, recounting advice Denzel Washington whispered to him at the ceremony:

"You don't want an award to improve your status. You want to improve the award's status." — Ethan Hawke quoting Denzel Washington, Variety (2024)

Roger — Scott Glenn

A retired narcotics detective and Alonzo's former partner, Roger lives quietly in a modest house with $4 million in cash hidden beneath the kitchen floor. He greets Alonzo as a friend, unaware that Alonzo has come to rob and kill him. Glenn plays Roger as a man who thought he was out of the game and discovers too late that the game never ended.

Sara — Eva Mendes

Alonzo's young girlfriend and the mother of his son. Sara lives in the neighborhood and represents the domestic life Alonzo maintains alongside his criminal operations. Her presence humanizes Alonzo briefly and gives Jake a glimpse of the man Alonzo might have been.

Smiley — Cliff Curtis

A Bloods gang leader in the Jungle who is ordered to kill Jake. Curtis plays Smiley as relaxed and lethal -- a man for whom violence is administrative, not emotional. When he discovers Jake saved his cousin from assault, he honors the debt and lets Jake walk.

Stan Gursky — Tom Berenger

One of the corrupt officers who participates in Roger's murder. Berenger plays Gursky as a man who has made his peace with criminality -- the institutional rot made flesh.

Casting could have gone very differently

The project was originally developed with Davis Guggenheim directing and Matt Damon and Samuel L. Jackson in the leads. When Washington came aboard, he requested Antoine Fuqua as director. Eminem declined the Jake Hoyt role to focus on preparing for 8 Mile. Tobey Maguire and Paul Walker also auditioned. (wikipedia)

Director Fuqua used unconventional methods to test Hawke's readiness:

"When I first sat down with him, the first thing he said was, 'Who's your Jake?'" — Antoine Fuqua, Cinema Daily US (2021)

Hawke, for his part, was determined:

"I'm going to get this part. I'm going to eat a little humble pie, and I'm going to go in and I'm going to get this part." — Ethan Hawke, The Ringer (2018)
