Anthony Pellicano, the former investigator known as Hollywood’s private eye to the stars, goes on trial on Thursday in a case of wiretapping and skullduggery that is expected to reveal the dark side of the glitzy world of the movie industry.

Actors Sylvester Stallone, Keith Carradine and Farrah Fawcett, along with movie studio executives Brad Grey and Ron Meyer and former powerhouse talent agent Michael Ovitz, are among the 120 prosecution witnesses called to testify in a case that has kept Hollywood on tenterhooks for almost six years.

Pellicano, 63, is accused of illegally wiretapping the telephones of opponents of his powerful clients and of bribing police officers and telephone company workers to run illegal background checks on the targets of his investigation.

Biggie is coming to the big screen.

Fox Searchlight has hired Jamal Woolard, a Brooklyn-based rapper, to play late rap icon Biggie Smalls, a.k.a. the Notorious B.I.G., in its upcoming biopic “Notorious.”

Derek Luke, Angela Bassett and Anthony Mackie also have been cast in the movie, the art-house studio said. Directed by George Tillman Jr. (”Soul Food”), it goes into production this month and is set for release in January.

Luke (”Catch a Fire”) will play Biggie record producer Sean “Diddy” Combs, who off-screen is an executive producer on the film. Mackie (”Brother to Brother”) will play rival rapper Tupac Shakur, while Bassett (”Akeelah and the Bee”) will play Biggie’s mother Voletta Wallace.

The production held an open casting call last fall in the hope of finding the next Notorious B.I.G., ne Christopher Wallace, the generously built East Coast rapper who was killed in an unsolved Los Angeles drive-by in 1997.

The idea, executives said, was that as with casting for sports movies like “Miracle,” the production would be better served with a non-actor who can rap and imitate Biggie than with a pro actor who might need to be taught how to rap.

More than 100 Biggie wannabes, many of them non-pros and all with the requisite size, turned out to show off their rapping and impersonation skills.

Woolard, who also is known as Gravy, is not a total unknown. He has released a number of albums, though he’s perhaps best known for being shot before a radio appearance outside the New York hip-hop station Hot 97 two years ago, after which he proceeded with the interview and became a part of hip-hop lore.

Like Biggie, Woolard was a drug dealer before he became a rapper. He had released a number of albums on indie labels in the 1990s before being signed by Warner Bros.

Voletta Wallace cited “Jamal’s charming personality, warm spirit, wonderful sense of humor and beautiful smile” as reasons for the casting. “He is a talented and charismatic actor, and I am excited that he will bring Christopher’s character to life,” she said.

Biggie, who drew on his experiences as a drug dealer in his rapping, is considered a seminal figure in the hip-hop world; his posthumously released “Life After Death” was a top seller and is considered one of the most influential hip-hop records of the modern era. “Notorious” is expected to examine his troubled life, his music and his impact.

In Hollywood, the math is never simple.

Worldwide box-office revenue rose to record levels last year, the studios’ main trade group said Wednesday — but a closer look at the numbers suggests a murkier picture of movie industry strength.

Movie ticket sales climbed to $9.6 billion in the U.S. and Canada and $26.7 billion globally, both logging 5% increases that demonstrated a “healthy” industry, said Dan Glickman, chairman of the Motion Picture Assn. of America.

The report tends to downplay the actual cost of making movies, however, along with currency fluctuations that benefited Hollywood because of the free-falling U.S. dollar.

For major studios, the average cost of producing and marketing a movie grew 6% to a record $106.6 million, the MPAA said. But that number — based on a survey of trade group members such as Walt Disney Co., 20th Century Fox and Paramount Pictures — reflects only the $70.8 million the MPAA said studios spent on a typical production and the $35.9 million they shelled out to advertise it and make prints.

Not considered was the tens of millions of dollars that outside partners such as Relativity Media, Legendary Pictures and Dune Capital Management spent to co-finance dozens of big movies, including last year’s “300″ and “American Gangster.” Studios are turning to partners such as hedge funds and banking firms to share in many of their productions, a strategy that limits their risk but also their potential profits.

Billions have poured into Hollywood since 2004, with all of the big studios and several of the smaller ones taking on partners for at least a portion of their films.

The MPAA has continued to tally only the investments by the studios, a calculation that analysts say glosses over the true expense of making movies.

Actor and dancer Patrick Swayze, star of such hit films as “Dirty Dancing” and “Ghost,” has been diagnosed with pancreatic cancer but is responding well to treatment, his publicist said on Wednesday.The 55-year-old performer was working during his treatments, publicist Annett Wolf said, dismissing reports in the tabloid media that portrayed him in grave condition with only weeks to live.

Wolf issued a written statement from his physician, Dr. George Fisher that said: “Patrick has a very limited amount of disease and he appears to be responding well to treatment.”

“All of the reports stating the timeframe of his prognosis and his physical side effects are absolutely untrue,” Fisher said in the statement. “We are considerably more optimistic.”

Wolf said Swayze deeply appreciated the “outpouring of support and concern” he has received from the public.

Though Swayze has had dozens of film, TV and stage roles, he is best known for starring as dance instructor Johnny Castle opposite Jennifer Grey’s character, infatuated teenager Frances “Baby” Houseman, in “Dirty Dancing.”

The film, which centers on an unlikely romance between the pair at a 1960s resort in the Catskills of New York, defied expectations to become a massive hit, earning both actors Golden Globe Award nominations.

Swayze performed the song “She’s Like the Wind” for the movie’s soundtrack and his signature line, “Nobody puts Baby in the corner,” has become a pop culture staple.

In “Tropic Thunder,” one of three summer films featuring Robert Downey Jr., the actor appears on screen as a black man.Downey Jr. plays overly committed actor Kirk Lazarus, a white man cast to play a black soldier in a satire of the performing profession. The film also stars Jack Black and Ben Stiller, who co-wrote, directed and produced it.

“If it’s done right, it could be the type of role you called Peter Sellers to do 35 years ago,” Downey told Entertainment Weekly magazine. “If you don’t do it right, we’re going to hell.”

Stiller said he was “trying to push it as far as you can within reality,” with the intent of satirizing over-the-top actors, not African-Americans.

“I had no idea how people would respond to it,” Stiller told the magazine. But at a recent screening, black viewers liked the film, he said.

Downey explained that he kept the character from becoming a caricature because he “dove in with both feet.”

“If I didn’t feel it was morally sound,” he said, “or that it would be easily misinterpreted that I’m just C. Thomas Howell in (”Soul Man”), I would’ve stayed home.”

Paramount is set to release “Tropic Thunder” Aug. 15.
