Chalk up another box-office record for The Dark Knight: the biggest gross for a film on a non-holiday Monday. Following a three-day weekend in which it raked in a record $158.4 million, the Warner Bros. movie added another $24.6 million on Monday to bring its total to $182.9 million after just four days. Many analysts were betting that it would easily cross the $200-million mark by the end of Tuesday, thereby setting yet another box-office record. (Results for Tuesday are expected to be announced later today.) The film's strong showing pushed the overall Monday box-office gross to $37.7 million, yet another record. Two films, Knight, and the musical Mamma Mia!, which earned $4 million, accounted for 76 percent of the total.

Mark Cuban, the co-owner of the Landmark Theatres chain, testified before an FCC panel on Tuesday that he foresees the day when live sports events will be presented in movie theaters in digital 3-D. Appearing at a hearing on "Broadband and the Digital Future" at Carnegie Mellon University in Pittsburgh, Cuban said that he presented a live 3-D broadcast of a Dallas Mavericks basketball game at a local Landmark theater in Dallas this past season. "It was a huge success. Fans loved it, 3-D glasses and all, and have asked for more," he told the panel. (Cuban is the owner of the Mavericks.) He remarked that what is holding back similar live telecasts is the virtual nonexistence of any production trucks dedicated to 3-D live programming. "So we are looking at building one," he said. He suggested that the technology could also be used for concerts and theatrical works.

Netflix is shutting down its Red Envelope Entertainment unit -- a two-year-old operation that invested in more than 100 independent films. The company said it was doing so because it competed against the studios that it relies on for its main movie-rental business. Netflix spokesman Steve Swasey said that the unit had been "very successful." Among the films that bear the Netflix logo are the recently released documentary Trumbo, the anti-war documentary No End in Sight, and the romantic comedy Two Days in Paris.

Darren Lynn Bousman, who directed three of the Saw movies, Zack Snyder, who directed the most recent iteration of Dawn of the Dead, and Andrew Douglas, who directed the latest Amityville Horror are among the directors who have signed deals with Microsoft to make a series of short films for Xbox Live. The movies are being produced by Safran Digital Group and are due to be shown in the 26 countries that support the Xbox Live service. The announcement comes just days after Microsoft said that it had struck a deal with Netflix to make thousands of films available for streaming online via the Xbox Live platform. In an interview with the London Financial Times, CEO Peter Safran said that the directors had been given complete creative control. "This is an opportunity that filmmakers don't usually get," he said.

Some 14.5 million people were singing "Take Me Out to the Ballgame" last week, making Fox's coverage of Major League Baseball's All-Star Game the most-watched telecast of the week. (The figure represented only the primetime segment of the telecast, which stretched past 1:00 a.m. as the game went into extra innings. From 11:00 p.m. to 1:00 a.m., it averaged 11 million viewers, more than the number that watched any other show in primetime during the week.) The game also helped Fox win the week, making it a rare win for the network during the summer months. Its Wednesday edition of So You Think You Can Dance also made it into Nielsen's top ten. Fox averaged a 4.5 rating and an 8 share for the week. CBS placed second with a 4.3/8. NBC took third place with a 3.6/7, while ABC trailed with a 2.9/5.

The top ten shows of the week according to Nielsen Research: 1. Major League Baseball All-Star Game, Fox, 9.3/16; 2. America's Got Talent, NBC, 7.9/13; 3. MLB All-Star Game Pregame Show, Fox, 6.8/13; 4. Criminal Minds, CBS, 6.2/11; 5. CSI: Crime Scene Investigation, CBS, 6/10; 6. CSI: NY, CBS, 5.7/10; 7. 60 Minutes, CBS, 5.6/11; 7. So You Think You Can Dance (Wednesday), Fox, 5.6/10; 9. Two and a Half Men, CBS, 5.5/9; 10. Dateline (Sunday), NBC, 5.3/9; 10. (tie) NCIS, CBS, 5.3/10.

ABC and NBC wound up in a virtual tie for first place among the three nightly newscasts. Nielsen gave them an identical 5 rating and 11 share and noted that NBC Nightly News with Brian Williams averaged 7.23 million viewers, while ABC's World News With Charles Gibson drew 7.22 million. The difference was statistically insignificant. CBS Evening News with Katie Couric remained substantially behind with 5.5 million viewers.

Raising new questions about the viability of online video as a revenue source, the sales manager of Google's YouTube has told the ClickZ conference on online video in New York that his sales team has been able to sell ads against less than 3 percent of the videos posted on the site. Brian Cusack also disclosed that the biggest advertisers are television networks, who presumably are buying spots to hype their television shows, and movie studios. Cusack also said that the YouTube sales staff has also begun "making progress" with other advertisers, including home improvement retailers, who buy ads against "how to" videos. The Silicon Valley Insider observed today that many of the biggest viral hits on the site, like last week's "Homemade Porn" video, run without advertising.

The Walt Disney Co. has wasted no time in finding replacements for Roger Ebert and Richard Roeper as hosts of the syndicated Ebert & Roeper and the Movies. Two days after Roeper quit the show and one day after Ebert did -- he has actually not appeared on it since a 2006 operation left him unable to speak -- Disney said that they will be succeeded by Ben Lyons, currently a film critic for E! Entertainment channel and Ben Mankiewicz, who hosts a movie discussion show on the cable network TCM (Turner Classic Movies). Disney also said that the show will be revamped, with a new set, graphics and theme and that a new segment will be added in which the two hosts will discuss new movies by satellite with other film critics. A spokeswoman for Disney-ABC Domestic Television, which syndicates the show, denied earlier reports that Ebert & Roeper and the Movies will be converted into an entertainment magazine show along the lines of Entertainment Tonight.

Estelle Getty, best known for her role as Bea Arthur's mother Sophia on The Golden Girls, died Tuesday in Hollywood at age 84. She was only 60 when she auditioned for the role, and an Associated Press obituary noted that she had originally been turned down by the producers because she didn't look old enough to play a woman in her 80s. She returned for another audition, telling a makeup artist, "To you this is just a job. To me it's my entire career down the toilet unless you make me look 80." Real life was not as kind to Getty in her 80s as it was to her character. Her son, Carl Gettleman, told the AP that she had been suffering from advanced dementia.

The Australian Broadcasting Corporation said today (Wednesday) that it had reached a turning point in the digital age with the launch of an online streaming platform that will enable viewers to watch a variety of its programs on demand. The iView platform offers channels for children's shows, documentaries, shopping, news, arts and "Catch-up" (where viewers can see ABC programs they may have missed in recent weeks). Kim Dalton, director of television for ABC, said in a statement that the iView platform is "about reaching our audience with unique quality content, where they want it, when they want it, and how they want it."
