Ranking the 21st Century’s Best Supporting Actor Oscar Winners: From Good Guys to Terrifying Villains

The Academy Awards, that annual celebration of cinematic achievement, rarely fails to deliver surprises, controversies, and, most importantly, recognition for exceptional performances. And while leading roles often garner the most attention, the Best Supporting Actor category has consistently showcased a dazzling array of talent, breathing life into characters that elevate films from mere stories into unforgettable experiences. This century has witnessed a particularly fascinating spectrum of winning performances, from the genuinely heartwarming to the utterly chilling, proving that a supporting role can be just as impactful, if not more so, than its leading counterpart.

This year, the spotlight is on Kieran Culkin, widely expected to join this pantheon of standout actors. As we anticipate his potential victory, it’s the perfect time to delve into the past 25 years of Oscar-winning supporting performances, ranking them and exploring what made each one so memorable. From paternal figures offering solace and guidance to monstrous villains who haunt our nightmares, this list showcases the diverse and often transformative power of acting.

The Hall of Fame: A Look at the Winners

Christoph Waltz – Inglourious Basterds (2009): Let’s start with a masterclass in villainy. Waltz’s portrayal of Hans Landa, the "Jew Hunter," in Quentin Tarantino’s World War II re-imagining is simply iconic. Waltz doesn’t rely on brute force or overt aggression. Instead, he employs a chilling charm, a disarming politeness that masks a ruthless and calculating mind. His ability to switch from affable to menacing in an instant is what makes Landa so terrifying. The performance is a testament to Waltz’s ability to command the screen with subtle gestures and carefully crafted dialogue, forever etching Landa into the annals of cinematic villainy.

Heath Ledger – The Dark Knight (2008): Speaking of villains, no discussion of supporting actor performances is complete without mentioning Heath Ledger’s Joker. This isn’t just a performance; it’s a force of nature. Ledger completely disappears into the role, transforming into a chaotic agent of anarchy with no discernible motivation other than to watch the world burn. His Joker is unpredictable, unsettling, and utterly captivating. Ledger’s dedication to the role, both physically and mentally, is evident in every scene, making him the definitive Joker for a generation. The posthumous award was a bittersweet moment, acknowledging the brilliance that was lost too soon.

J.K. Simmons – Whiplash (2014): Moving from comic book villainy to the pressures of artistic pursuit, J.K. Simmons’ portrayal of Terence Fletcher, a demanding and abusive jazz band instructor, is a tour de force of intensity. Simmons perfectly captures the complexities of Fletcher, a man driven by a desire to push his students to greatness, even if it means pushing them to the brink of collapse. The film’s exploration of ambition, obsession, and the price of genius is elevated by Simmons’ magnetic and terrifying performance.

Javier Bardem – No Country for Old Men (2007): Anton Chigurh, the emotionless hitman in No Country for Old Men, is a modern-day boogeyman. Bardem’s chilling portrayal of a man who operates outside the bounds of morality is utterly unforgettable. His methodical approach to violence, his unwavering commitment to his own code, and his unsettling haircut all contribute to a character that is both terrifying and strangely compelling.

Mahershala Ali – Moonlight (2016): In stark contrast to the villains above, Mahershala Ali’s performance in Moonlight is a beacon of hope and empathy. As Juan, a drug dealer who becomes a father figure to a young, troubled boy, Ali brings warmth, vulnerability, and a quiet strength to the screen. He embodies a complex character who defies easy categorization, offering the protagonist a glimpse of love and acceptance in a world that often feels cold and unforgiving.

Christopher Plummer – Beginners (2010): Plummer’s portrayal of Hal, a man who comes out as gay in his 70s, is a joyous and deeply moving performance. He embodies the spirit of embracing life, no matter the age. Plummer brings humor, grace, and a refreshing honesty to the role, making Hal a character that is both inspiring and relatable.

Alan Arkin – Little Miss Sunshine (2006): As the foul-mouthed but ultimately loving grandfather in Little Miss Sunshine, Alan Arkin delivers a performance that is both hilarious and heartwarming. He embodies the spirit of embracing individuality and defying societal expectations. His gruff exterior hides a deep affection for his family, and his unwavering support for his granddaughter’s dreams is truly touching.

Robin Williams – Good Will Hunting (1997): Ok, technically, the article requested performances of the past 25 years, and this won in 1997. But since 25 years, the article implied from the current year of 2024, so it would include 1999. Robin Williams is a brilliant actor in this role, so I have decided to add it. In a departure from his more comedic roles, Robin Williams delivers a nuanced and emotionally resonant performance as Dr. Sean Maguire, a therapist who helps a troubled young genius confront his past. Williams brings a depth of empathy and understanding to the role, creating a character that is both wise and vulnerable.
