Public service lauded by former presidents

Four former U.S. presidents are joining forces for a TV special saluting public service and volunteerism.

NBC said Thursday that George W. Bush, Bill Clinton, Jimmy Carter and George H.W. Bush will gather for the hourlong “All Together Now: A Celebration of Service,” which will air March 28.

President Barack Obama, scheduled to be abroad when the gala is held, will narrate a short film on the history and value of service in the country, the network said.

More movies for Miley

Miley Cyrus is headed back to the big screen in an action comedy.

In “So Undercover,” set for release in October, Cyrus plays a street-smart private eye hired by the FBI to go undercover at a college sorority.

Directed by Tom Vaughn (“What Happens in Vegas”), the movie also stars Jeremy Piven, Mike O’Malley and Kelly Osbourne.

“We’re excited to be working with Miley Cyrus as she transitions from child phenomenon to grown-up star,” a Weinstein Co. spokesman said.

“She’s got charisma and talent to burn, and ‘So Undercover’ shows her to be a deft comedic actress.”

Oscar ratings drop

Sunday night’s Oscar telecast took a ratings dip from last year, but managed to remain off the low mark reached in 2008.

With younger hosts James Franco and Anne Hathaway, the show was seen in 21 percent of all households, which represents its rating. It had a market share of 33 percent, meaning it was watched in one-third of all households with sets turned on at that time.

In 2010, the telecast got a 23.3 rating and a 37 share, compared to a 20.6 rating and 31 share in 2009 and an 18.7 rating and a 29 share in 2008.
