Acclaimed actor-director Richard Attenborough has died at 90, the actor's agent said. Attenborough is perhaps best known for his work on the 1982 film "Gandhi," which won eight Academy Awards, including best picture and best director. The film took Attenborough some 20 years to make. "I was bankrupt several times. I had to mortgage my house. My family suffered to a certain extent," he said. "I placed things at risk because I cared about it so much." He died Sunday, according to his agent, Dallas Smith. The family is expected to make a statement Monday, Smith told CNN. "Our thoughts are with them and his friends at this very sad moment as we mourn the passing of a truly great man of the cinema and the arts," Smith said. Attenborough began his career as a classically trained English actor and went on to star in such films as "The Great Escape," "Jurassic Park" and a remake of "Miracle on 34th Street." He was knighted in 1976. British Prime Minister David Cameron tweeted Sunday: "His acting in 'Brighton Rock' was brilliant, his directing of 'Gandhi' was stunning -- Richard Attenborough was one of the greats of cinema." The cause of his death was not immediately clear. Attenborough's marriage to actress Sheila Sim spanned seven decades and produced three children. "My philosophy has always been that I believe that art is not an elitist gift for a few select people. Art is for everyone," he once said. Attenborough also appeared as Santa Claus in the 1994 remake of "Miracle on 34th Street." After playing several characters in movies, he moved to the other side of the camera. "It's what I love. I'm not a great movie director. I'm not an auteur," he said of directing. "I'm a storyteller. I'm a craftsman. And I love beyond anything else working with the actors and finding a way to make the actor believe that what they're about to do is the best performance they've ever given." He also appeared in several war movies, including "The Great Escape" with Steve McQueen. People we've lost in 2014.

The National Basketball Association is one of the pre-eminent sport leagues in the world and every Thursday, Bleacher Report will bring you a round-up of all the action on and off court Stateside. Newsmaker. The incensed version of Derrick Rose took centre stage following the Chicago Bulls' 108-94 loss to the Cleveland Cavaliers on Monday night. In speaking with reporters after the game, he expressed his frustration in no uncertain terms. Rose said: 'We've got to give a better effort. It seems like we're not even competing and it's f***ing irritating. We're midway through the season; no excuses; when you don't have that edge you are going to get your (butt) whipped.' Questioning effort is a great way to set a locker room ablaze. Whether the ignited fire has its intended impact is a different story. Derrick Rose expressed his frustration at the Chicago Bulls' defeat by the Cleveland Cavaliers. The Bulls were beaten 108-94 by their Eastern Conference rivals on Monday in Ohio. Good Week. The Atlanta Hawks matched the all-time franchise record of a 14-game winning streak with victory over the Indiana Pacers on Wednesday. The 35-8 Hawks have surprisingly emerged as the hottest team in the NBA, using the recent stretch of phenomenal basketball to build a healthy lead over the Washington Wizards for the top seed in the Eastern Conference. With centre Al Horford leading the way, Atlanta matched a franchise record set back in 1993-94, when the team went 57-25 before losing to none other than the Pacers in the second round of the play-offs. The Atlanta Hawks beat the Indiana Pacers to extend their winning streak to 14 games. Bad Week. The Milwaukee Bucks have been among the NBA's most pleasant surprises this season, but maintaining their high level of play may prove difficult as the league has suspended center Larry Sanders. The 26-year-old big man will miss at least 10 games after violating the NBA's drug policy: this marks the second time in as many seasons that the league has disciplined Sanders, his 2013-14 suspension coming due to marijuana use. To be clear, the league has not announced what Sanders tested positive for in this instance. Sanders' suspension will continue 'until he is in full compliance with his treatment program' Sanders' production has dropped off a bit over the past two seasons after an excellent 2012-13 campaign, but he is still an important player for the Bucks. The Milwaukee Bucks saw their center Larry Sanders suspended by the league. The Bucks thrashed the New York Knicks when they met at London's O2 Arena last week. Brit Watch. Miami Heat veteran forward Luol Deng is currently dealing with an illness that kept him out of Wednesday's game. Although not quite the player he once was with the Chicago Bulls, Deng has continued to serve as a solid two-way player in his first season with the Heat. Injuries, however, are beginning to take their toll on the 29-year-old. He missed 19 games with a variety of afflictions last season and was hampered earlier this year by a hand injury. Britain's Luol Deng missed Miami Heat's game at the Charlotte Hornets through injury. And Finally. Being 34-years-old doesn't make one a senior citizen, but for Jason Richardson of the Philadelphia 76ers, it makes him quite a bit older than his team-mates. That's why the young Sixers had some fun with their veteran teammate on his birthday. To celebrate Richardson's birthday, 76ers players gave him adult diapers, a robe and baby food. Richardson (born in 1981), Andrei Kirilenko (1981), Luc Mbah a Moute (1986) and Malcolm Thomas (1988) are the only players on Philadelphia's roster who were not born in the 1990s. Kirilenko has yet to report to the team since being traded to Philadelphia earlier this season, so Richardson is the oldest player on the team by a good margin.
