No person in Oscar history has received more nominations without a win than this sound mixer, whose 21 noms span 33 years, and who explains how he does what he does and why the Academy's voting process has room for improvement. (2/26/17 update: O'Connell finally won!)

The 32-year-old, who already has directed two best picture Oscar nominees and is poised to become the youngest best director Oscar winner ever, reflects on the roots of his passion for music and movies, the Harvard pal who became his closest collaborator and the rollercoaster of a journey to realizing his dream of making an original movie musical.

The 37-year-old who could become the first black person ever to win the best director Oscar reflects on how his tumultuous childhood has informed his work, the film school pals who have been by his side ever since and the causes and effects of the eight-year gap between his debut feature and his taboo-busting masterpiece.

The 'Meryl Streep of France,' finally an Oscar nominee at the age of 63, discusses her close collaborations with Claude Chabrol and Michael Haneke, her attraction to "perverse, manipulative, icy" characters and the controversial new film for which she's received the best notices of her career.

Poised to become, at 36, the youngest EGOT in history, the creator of 'Hamilton' reflects on that groundbreaking musical's origins and success, realizing his lifelong dream of writing music for a Disney movie while at the center of his show's "wonderful tsunami," the roots of his love of music and theater and the ambitions he has not yet fulfilled. (And yes, there will be a 'Hamilton' movie.)

The 28-year-old critics' darling and fan favorite opens up about overcoming "debilitating" childhood anxiety through acting, moving to Hollywood at 15 (and changing her name and dyeing her hair), finding magical chemistry with Ryan Gosling in three films and, under the oversight of Damien Chazelle, breathing new life into the American movie musical.

The 26-year-old Brit reflects on the life-changing impact of 'Slumdog Millionaire' — good and bad ("It was like being in a gold-plated cage") — and why he so aggressively pursued and transformed himself for the film for which he just became only the third person of Indian descent ever to receive an acting Oscar nom: "A script like this — a journey like this — is never gonna come around again."

The dashing star reflects on the ups and downs of 25-plus years in the biz, from the indie he calls "one of my favorite movies" to the studio bomb that "just never really understood what it was" to one of 2016's biggest blockbusters ("I was born to play this guy"), which could even land Oscar love ("I can certainly promise one fucking crazy reaction video").

The fan favorite on breaking through in 'Swingers,' not being seen as funny until after 'Old School' and 'Dodgeball,' the intention of 'The Break-Up' ("I really designed it to go from comedy to drama"), his decade in the cold ("I didn't follow through") and his career-reboot in Mel Gibson's acclaimed war film.

The Oscar-nominated veteran reflects on his early years of struggle as an actor, the tumultuous 'Lord of the Rings' production ("I don't think anybody knew it was gonna be the huge success it became"), turning down an invitation to join the Academy ("I've changed my mind since then") and the odds-defying success of the film for which he's received best actor Golden Globe, SAG, BAFTA and Spirit noms.

The legendary songwriter/composer behind 48 top 10 hits, including nine that topped the charts, opens up about the inspirations for his most beloved music, what caused his breakup with longtime collaborator Hal David and how his late daughter, who was afflicted with Asperger Syndrome, inspired him to write his first film score and song in years.

The trailblazing two-time Oscar winner dishes on the advice Sidney Poitier gave him early in his career, his "formula" for whether or not to make a movie, the #OscarsSoWhite controversy ("You don't want to be nominated just because you're black") and why he agreed to direct and star in a big screen adaptation of the play for which he won a 2010 Tony.

The star of the last two best picture Oscar winners reflects on his groundbreaking pair of 'Batman' films ("If it went down, we were going down in a big way"), walking away from a third ("It sucked"), his years in the cold ("Not a whole lot of folks were knocking on my door"), almost starring in 'Lost' and his great run over the last three years ('Birdman,' 'Spotlight' and now a Ray Kroc biopic).

Only one person ever has been Oscar-nominated for multiple songs featured in documentaries: this 41-year-old former prodigy with a social conscience second-to-none.

The 33-year-old discusses life pre-stardom ('I worked as a barista at Starbucks... and then I was fired'), 'The Social Network' (he originally was to play Mark Zuckerberg), his 'Spider-Man' films ("I didn't feel like that was my work up there") and his experiences with Mel Gibson and Martin Scorsese.

The 49-year-old Oscar winner reflects on her roots in Australia, her marriage to Tom Cruise, why her career flourished after their divorce and the personal reasons why she was so drawn to playing the adoptive mother of two Indian children in fellow Aussie Garth Davis' directorial debut.

25 years after her debut solo album 'Little Earthquakes' made her a star, the singer-songwriter reflects on her unusual upbringing, clashes with record industry execs and why she wrote the Oscar-contending song 'Flicker' for a Netflix doc about the sexual assault of young women.

The newly-minted Golden Globe nominee discusses growing up as Phil Collins' daughter, her distinct look (eyebrows!), early auditions (she lost parts in 'Twilight' and 'Snow White and the Huntsman' to Kristen Stewart) and proving her chops opposite Oscar winners (Sandra Bullock, Julia Roberts and this year, in his first film in decades, Warren Beatty).

The consummate entertainer reflects on his early appearances on 'Star Search' and 'Mickey Mouse Club,' the evolution and dissolution of N Sync ("I had something that I wanted to do that, quite honestly, I didn't think any of them would be interested in"), his pivot to acting and the creation of the biggest single of 2016, Oscar contender "Can't Stop the Feeling!"

The Critics' Choice Award nominee on why she hates the term 'mumblecore' ("I'm just waiting for the day that I never have to hear it again"), rejects the 'hipster' label ("I've never been cool enough to be a hipster") and agreed, to the surprise of many, to do 'How I Met Your Dad' ("Those guys saved my life").

The fast-rising actress (Oscar-nominated at 14 for 2010's 'True Grit') and singer (whose 2015 debut EP 'Haiz' was a hit) talks about child stardom (she auditioned for 'The Hunger Games'), balancing movies and music ("I don't see myself doing one and not the other"), plans to direct and the teen dramedy for which she just got a Golden Globe nom.

The British actor of Nigerian descent reflects on a childhood caught between two worlds, why he owes so much to George Lucas (and repeat-collaborators Lee Daniels and Ava DuVernay), the 'Selma' "snub" ("The films I do very quickly get politicized") and his latest project: Disney’s first live-action film made with an all-black cast and/or set and shot in Africa.

The single most influential person in the history of doc filmmaking reflects on how a gig that was to last 13 weeks has gone on for more than 30 years, how the arrival of Vice at HBO and the rise of streaming services like Netflix and Amazon has impacted her division and what she thinks the future holds — for her, her division and doc filmmaking in general.

One of Hollywood's most bankable young stars reflects on his early pretty-boy roles ("I had no fucking interest in all these"), his failed audition for 'Avatar' ("I was just awful"), almost turning down 'Star Trek' ("I was scared") and finding his best part yet in a modern-day Western ("the only experience I've had where I knew I had to do it").

The 65-year-old rock star reflects on how he got his nickname ("It was derisory"), why he disbanded The Police ("My intuition was telling me that that was the thing to do") and how, over Thanksgiving dinner, he came up with the song that could bring him his fourth Oscar nom.
