Cast of The Hangover: Full List of Actors and Characters

Few comedies from the late 2000s still spark the same mix of laughter and disbelief as The Hangover, a trilogy released in 2009, 2011, and 2013 that turned a simple bachelor-party-gone-wrong premise into a global phenomenon thanks to its mismatched trio and supporting cast. Whether you’re revisiting the Wolfpack or meeting them for the first time, here’s every key actor and role across all three films.

Release Year (Part I): 2009 ·
Director: Todd Phillips ·
Box Office Revenue (Part I): $467 million ·
Main Cast Members (Part I): 6

The trilogy spans just three years of releases, but the cast changed and expanded in notable ways. Here’s a quick reference table of the core details.

Who are the main cast members of The Hangover?

Bradley Cooper as Phil Wenneck

• Role: The confident, fast-talking teacher who drives the group’s energy.
• Appears in: All three films.
• Source: Wikipedia actor page

Cooper’s Phil is the unofficial leader of the Wolfpack, often taking charge when things spiral. His chemistry with Helms and Galifianakis anchors the trilogy’s comedy. The role launched Cooper into A-list territory, leading to four Oscar nominations in subsequent years.

Ed Helms as Stu Price

• Role: The nervous dentist who gets the worst of the hangover aftermath.
• Appears in: All three films.
• Source: Wikipedia actor page

Stu provides the trilogy’s emotional anchor and much of its slapstick — from a missing tooth in the first film to a tattoo he can’t explain in the second. Helms brought a vulnerable everyman quality that balances Alan’s chaos.

Zach Galifianakis as Alan Garner

• Role: The eccentric, socially clueless brother-in-law who steals every scene.
• Appears in: All three films.
• Source: Wikipedia actor page

Galifianakis’s Alan is the breakout character — he delivers the trilogy’s most quoted lines and physical comedy. The role earned him a Golden Globe nomination and defined his career persona.

Justin Bartha as Doug Billings

• Role: The groom who goes missing for most of the first film.
• Appears in: All three films (though with less screen time in the first).
• Source: Wikipedia actor page

Doug is the MacGuffin of the original film — the gang’s mission is to find him. Bartha’s screen time increases in the sequels, where he becomes more involved in the action.

Heather Graham as Jade

• Role: The stripper with a heart of gold who marries Stu in a drunken Las Vegas ceremony.
• Appears in: The Hangover and The Hangover Part III.
• Source: Wikipedia actor page

Graham’s Jade is a memorable supporting character, though she is absent from the second film. She returns briefly in the third installment.

Jeffrey Tambor as Sid Garner

• Role: Alan’s father and Doug’s future father-in-law.
• Appears in: The Hangover only.
• Source: Wikipedia actor page

Tambor brings his trademark dry humor to the role of Sid, who has a memorable confrontation with Alan about his behavior.

What this means: The core trio plus Bartha form the Wolfpack, but the supporting characters — Graham, Tambor, and others — give the world its texture. Without them, the Vegas adventure would feel thin.

Who is in the cast of The Hangover 2?

Bradley Cooper as Phil, Ed Helms as Stu, Zach Galifianakis as Alan, Justin Bartha as Doug

• All four return for the Bangkok-set sequel.
• Source: IMDb Part II page

The core quartet carries over, but the sequel introduces new faces that shift the group dynamics.

Ken Jeong as Leslie Chow

• Role: The flamboyant Chinese gangster who becomes a major irritant.
• Appears in: All three films (promoted to main cast in sequels).
• Source: Wikipedia actor page

Jeong’s Chow steals the sequel with his unpredictable energy. Originally a minor character in the first film, he becomes a central figure in Part II and Part III.

Paul Giamatti as Kingsley

• Role: A vengeful crime boss whose son was killed.
• Appears in: The Hangover Part II only.
• Source: ScreenRant movie guide

Giamatti brings dramatic weight to the sequel as the antagonist who threatens the Wolfpack. His performance contrasts with the film’s broader comedy.

Why this matters: The second film expanded the cast without losing the core, but the new characters — especially Chow — became essential to the trilogy’s ongoing story.

Who is in the cast of The Hangover 3?

Returning main cast

• Bradley Cooper, Ed Helms, Zach Galifianakis, Justin Bartha all reprise their roles.
• Source: TV Guide cast list

Ken Jeong as Leslie Chow

• Returns as the scene-stealing criminal.
• Source: Wikipedia Part III page

John Goodman as Marshall

• Role: A ruthless crime lord who forces the Wolfpack to track down Chow.
• Source: Wikipedia actor page

Melissa McCarthy as Cassie

• Role: A sassy police officer who assists the gang.
• Source: Wikipedia actor page

The third film shifts away from the “hangover” premise and becomes a road-trip crime comedy. The addition of Goodman and McCarthy brings seasoned comedic talent to the finale.

The pattern: Each sequel added bigger names — Giamatti, Goodman, McCarthy — but the trilogy’s identity remained rooted in the dysfunctional chemistry of the original Wolfpack.

Who played the baby in The Hangover?

• The baby character, named Tyler, is the infant Doug and Jade had in the first film.
• Portrayed by twins Grant Holmquist and Mason Cook.
• Source: IMDb full credits

Twin babies are commonly used in film to comply with child labor restrictions. The Holmquist and Cook twins shared the role, appearing in the film’s closing scene.

The catch: Neither twin pursued acting further; their appearance remains a trivia footnote for fans.

Who directed The Hangover?

• Todd Phillips directed all three films.
• Source: Wikipedia director page

Phillips, known for Old School and later Joker, brought a raucous yet character-driven approach to the trilogy. He also appears in a cameo as Mr. Creepy in The Hangover Part III.

Why this matters: Phillips’s consistent direction ensured tonal continuity across the three films, even as the franchise evolved from a simple comedy into a globe-trotting farce.

Wikipedia film series entry

For anyone looking to revisit the trilogy, the cast remains the anchor of its enduring appeal. Without the chemistry of Cooper, Helms, and Galifianakis, the franchise would not have sustained its box office momentum. For new viewers, the clear takeaway: the Wolfpack is the heart, and the supporting players – from Heather Graham to John Goodman – are the spice that keeps every rewatch fresh.
