JON STEWART: John Oliver is to fill in for Jon Stewart when "The Daily Show" host takes a 3-month break from the New York show to direct his first film, Deadline reported.
Stewart penned the script for "Rosewater," which is based on the book "Then They Came For Me: A Family's Story of Love, Captivity and Survival" by Maziar Bahari.
Bahari is the BBC journalist who left London in June 2009 to cover Iran's presidential elections for a week and instead spent 118 days in an Iranian prison being brutally interrogated, Deadline said.
Oliver is to tape eight weeks worth of "Daily Show" episodes while Stewart is making the film, the website said.
GEORGE CLOONEY: Hollywood actor-director George Clooney has started shooting "The Monuments Men" in Germany, Columbia Pictures and Twentieth Century Fox said Tuesday.
The action-thriller is written by Clooney and his producing partner Grant Heslov. It is based on the book by Robert M. Edsel with Bret Witter.
Clooney and Heslov are also producing the film through their Smokehouse Productions. The production is their first since winning the Academy Award for Best Picture last month for their work on "Argo."
Starring Matt Damon, Bill Murray, Cate Blanchett, Jean Dujardin, Bob Balaban, Hugh Bonneville and John Goodman, "The Monuments Men" is based on an unlikely World War II platoon, tasked by President Franklin D. Roosevelt with going into Germany to rescue artistic masterpieces from Nazi thieves and returning them to their rightful owners, a synopsis said.
Filming is to take place in Germany and the United Kingdom through the end of June. The movie is scheduled for North American release Dec. 18.
