The Titanic star portrays notorious plantation boss Calvin Candie, who forces his male workers to fight for sport and pushes his female servants into prostitution, and DiCaprio admits he had reservations about how far he wanted to take the character.
The actor struggled to relate to anything about Candie and that made his job even more difficult onscreen.
He says, "It was this incredibly interesting horrific character. I mean, there was absolutely nothing about this man I could identify with. I hated him and it was one of the most narcissistic, racist characters I've ever read in my entire life."
DiCaprio reveals he almost chose to soften his character - but was persuaded to stick to his tough approach by Foxx and Jackson, who both play slaves, because there really were slave masters like that throughout American history.
He continues, "One of the pivotal moments for me was this initial read through, I wondered if it needed to be this violent and this atrocious to other human beings and it was Sam and Jamie who said, 'If you sugarcoat this people are gonna resent the hell out of you. You got to push this guy to the outer extreme.' That is what ignited me into going the way I did into the character. Once I read about the sugar plantations (in history), we're just scratching the surface of what happened in this country."
DiCaprio was also hesitant about using the 'N' word repeatedly, as dictated by Tarantino's script, but Jackson let him know none of his black co-stars were offended by the racially derogative term because it was the language of that time.
Foxx explains, "At one point he (DiCaprio) was feeling it was tough saying his lines, 'n**ga, n**ga' and Samuel pulled him aside and says, 'Hey motherf**ker, this is another Tuesday for us. Let's go!' They were really trying to go back to that time."
The actor sliced open his hand while filming a dramatic scene as ruthless plantation owner Calvin Candie in Quentin Tarantino's upcoming Western.
Producer Stacey Sher tells Variety.com, "Leo had slammed his hand on the table countless times and he moved his hand further and he crushed a crystal cordial glass. Blood was dripping down his hand. He never broke character. He kept going. He was in such a zone. It was very intense. He required stitches."
Sher is convinced audiences will love DiCaprio's performance, adding, "Quentin has this great tradition of villains in his films and Calvin Candie is one of the most vibrant he's ever created. Leonardo didn't shy away from playing all of the different facets of a truly horrible human being. Their collaboration raised the stakes and made for an exciting atmosphere on set."
"As I was putting it on 15 years ago I realised... If I added up what all the clothes in my life were worth, they wouldn't be as much as the suit I was putting on... That was kind of the first moment my life got really surreal." Matt Damon was thrilled when designer Calvin Klein sent him a free suit to wear to an awards ceremony following the actor's breakthrough in Good Will Hunting.
The Pulp Fiction director and DiCaprio have been looking out for projects to work on for years and the actor took a long hard look at Tarantino's Inglourious Basterds script and considered playing the war film's bad guy Hans Landa - the role which eventually went to Christoph Waltz.
The stars finally aligned for the two Hollywood heavyweights when the filmmaker realised his first choice for slave boss Candie was too old.
He tells Playboy magazine, "When I finished the script I realised they (actor) were a little older than I wanted the character to be.
"That's the problem I have. I'll be thinking about somebody and not take into account that I'm thinking of them from 20 years ago. Leo was younger than I had initially written, but I read it (script) again and could see no reason why the character couldn't be younger.
"He was curious about playing the role (of Landa in Inglourious Basterds), but I knew I needed somebody with all those linguistic skills. Leo can actually speak good German, but Landa spoke French in the movie more than German.
"Leo and I have hung out over the course of 15 years, and he likes my writing and makes sure he gets a copy of scripts I finish to see if there's anything that might float his boat. He got this one and really liked Calvin Candie."
Teri Shields, who died in New York City last week (31Oct12), guided her young daughter to fame, putting Brooke in the spotlight at just 11 months old in a soap advertisement.
She later became the actress' manager and helped Brooke land a controversial part as an underage prostitute in 1978's Pretty Baby, as well as a suggestive 1980 Calvin Klein campaign.
Teri faced a backlash for allowing her daughter to take on the provocative jobs, but Brooke is adamant her mother did not deserve such harsh criticism.
Speaking to The Hollywood Reporter after her mother's death, she says, "She protected me from so much of what is devastating about being in the entertainment industry - the rejection, the jealousy, the being s**ewed-over. The bubble she created around me was the biggest blessing she could have given me. The need to attack her is unnecessary."
Mother and daughter parted ways professionally in 1995 after their relationship became strained due to Teri's struggle with alcoholism, and Brooke adds, "I had to leave her because of her addiction. If I had a manager now, they wouldn't last five minutes if they were an alcoholic. It was long overdue. I needed to grab the reins and make my own mistakes."
The style mogul was forced out of his luxury triplex penthouse in Manhattan when the massive storm hit America's East Coast last week (ends04Nov12), and residents of the Perry Street building have now been told it could be months before their homes are deemed habitable again.
The basement has reportedly flooded, the elevators are broken, and the building's electrical system has also been damaged.
A source tells the New York Post's gossip column Page Six, "All the mechanics for the buildings are underground and flooded. While his apartment was not damaged, the building is not habitable. Calvin was told they will be displaced for six months."
Former high-profile residents of the building, which was designed by star architect Richard Meier, include Jim Carrey, Hugh Jackman, Sir Paul McCartney's ex-wife Heather Mills, and Nicole Kidman, who sold her apartment there earlier this year (12).
The Hours star Moore took to the stage at the Cipriani venue in New York City to present Calvin Klein Collection designers Francisco Costa, Italo Zucchelli and Ulrich Grimm with the Designer of the Year Award.
TRON: Legacy beauty Wilde presented the Visionary Award to footwear designer Vince Camuto in front of a star-studded audience including actor Kyle MacLachlan and actresses Katrina Bowden and Tika Sumpter.
The Vogue covergirl broke down and sobbed in a restroom during the shoot for fashion magazine The Face after being commanded to strip or face never working in the industry again.
In a rare interview, Moss, now 38, looks back on the traumatic event that shaped her career when she was a naive 16 year old trying to break into the modelling world.
She tells Vanity Fair magazine, "I hated my boobs because I was flat-chested, and I had a big mole on one. But they said, 'If you don't do it, we're not going to book you again'.
"I'd lock myself in the toilet and cry, then come out and do it. I made the hairdresser - the only man - turn his back."
It previously emerged on Wednesday (31Oct12) that Moss suffered a meltdown when she was 17 after stripping off for the iconic Calvin Klein underwear campaign in 1992 alongside Mark Wahlberg, then known as rapper Marky Mark.
The style icon and former face of Calvin Klein has always flaunted a slim figure, even after becoming a mum to daughter Lila Grace a decade ago, leading many critics to believe Moss kept her weight in check by dabbling with anorexia.
However, the 38 year old has now set the record straight, admitting she would have been dropped from her job if she began relying on drastic measures to stay skinny.
She tells Vanity Fair magazine, "You'd get to work in the morning, there was no food. Nobody took you out for lunch when I started... but I was never anorexic.
"They (fashion bosses) knew it wasn't true - otherwise I wouldn't be able to work. I was thin, but that's because I was doing shows, working really hard."
Moss has also blasted reports she took drugs to stay thin at the height of her modelling career: "I had never even taken heroin - it was nothing to do with me at all."
The Brit became the world's most in-demand model after she stripped off for her iconic Calvin Klein campaign with rapper Wahlberg in the 1990s, but she admits the job traumatised her.
She tells Vanity Fair magazine, "I had a nervous breakdown when I was 17 or 18 - when I had to go and work with Marky Mark. It (the job) didn't feel like me at all. I felt really bad about straddling this buff guy. I didn't like it. I couldn't get out of bed for two weeks. I thought I was going to die. I went to the doctor and he said, 'I'll give you some Valium.'
"It was just anxiety. Nobody takes care of you mentally. There's a massive pressure to do what you have to do (and) I was really little ... I didn't like it. But it was work, and I had to do it."
The blonde beauty found solace in actor Johnny Depp when they began dating in 1994, but she was left heartbroken when they split after four years.
She recalls, "Johnny took care of me. If I said, 'What do I do?' he'd tell me. (After the break-up) I really lost that gauge of somebody I could trust. Years and years of crying. Oh, the tears!"
