As we look back on the cinematic landscape of the late 20th century, few years shine as brightly as 1999. This year was not just the end of a millennium but a remarkable moment in film history, showcasing innovation, depth, and performances that have since become legendary. While the spotlight often falls on lead actors, the supporting roles of 1999 brought depth and gravitas to their films, often stealing scenes and sometimes the whole show. Here, we celebrate the Top 10 Performances in a Supporting Role from that iconic year, each a vital piece of the cinematic mosaic that made 1999 a landmark year for movies.
10. John Malkovich in “Being John Malkovich”
Malkovich’s performance as a version of himself trapped within the surreal, meta-fictional universe of Charlie Kaufman’s script was nothing short of a revelation. His ability to be both the puppet and the puppeteer, offering a nuanced portrayal of vulnerability, confusion, and ego, set a high bar for the year.
9. Toni Collette in “The Sixth Sense”
Collette’s portrayal of Lynn Sear, the struggling, single mother of a boy who “sees dead people,” is deeply moving. Her raw, emotional depth grounds the film’s supernatural elements in profound human experience, making the film’s twists all the more impactful.
8. Michael Clarke Duncan in “The Green Mile”
As John Coffey, the gentle giant with a mysterious healing gift, Duncan brought tenderness and gravity to a role that could have easily become clichéd. His performance was a critical element in one of the year’s most emotionally resonant films.
7. Haley Joel Osment in “The Sixth Sense”
Though arguably the lead alongside Bruce Willis, Osment’s role feels integral yet supporting, given Willis’s character’s arc. His delivery of the iconic line, “I see dead people,” is chillingly mature, anchoring the film’s haunting atmosphere.
6. Catherine Keener in “Being John Malkovich”
Keener’s Maxine is a masterclass in manipulation, seduction, and the complexities of desire. Her performance adds an essential layer of intrigue and darkness to the film’s already twisted premise.
5. Samantha Morton in “Sweet and Lowdown”
As Hattie, the mute laundry woman who becomes the object of a self-absorbed musician’s affection, Morton delivers a performance of captivating silence. Her expressive face communicates volumes, providing a poignant counterpoint to Sean Penn’s verbose guitar virtuoso.

4. Tom Cruise in “Magnolia”
As the misogynistic self-help guru Frank T.J. Mackey, Cruise took on a role far removed from his typical hero persona. His portrayal of vulnerability, anger, and sorrow beneath a veneer of confidence and charisma is both shocking and deeply moving.
3. Angelina Jolie in “Girl, Interrupted”
Jolie’s Oscar-winning turn as the charismatic, manipulative Lisa Rowe is electric. She embodies the chaos and danger of mental illness while also conveying an underlying pain and fragility that’s hard to ignore.
2. Philip Seymour Hoffman in “Magnolia”
Hoffman’s role as the compassionate nurse Phil Parma exemplifies his ability to bring warmth and humanity to every character he played. In a film filled with larger-than-life performances, his subtlety and depth provide a grounding presence.
1. Christopher Plummer in “The Insider”
In a film about truth and the heavy costs of uncovering it, Plummer’s portrayal of “60 Minutes” journalist Mike Wallace is a towering achievement. He captures the complexities of journalism ethics, ambition, and the personal toll of the profession with unparalleled skill and nuance.
