FLICKS FILM AND VIDEO FILE : Diners’ Flub : ‘Candid Camera’ plays some tricks on unsuspecting patrons at a Camarillo restaurant.

Customers at Joanie’s restaurant in Camarillo were all smiles Saturday. After all, you have to smile when you’re on “Candid Camera.”

A crew from the King World Productions television show, which catches people in the act of looking silly, dropped in on the Ventura Boulevard diner and filmed six hours of material. The story line for the day: A “patron” (actor Jim Nixon) kept asking other patrons (unsuspecting customers) to taste his food.

Joanie Dehaas, co-owner of the restaurant, said about 15 people, including herself, were caught on camera. She said most took the practical joking in stride.

“They were all willing except the first one who did it. He got upset,” Dehaas said. “He said, ‘I am not going to taste your food and I don’t want you to bother me.’ When he found out it was ‘Candid Camera,’ he was still upset. He would not sign the release.”

Classic Cinema returns to the Thousand Oaks Library on Saturday with the 1981 German film “Circle of Deceit.” It stars Bruno Ganz as a German journalist covering the civil war in Lebanon and looks at how he is affected by the violence. The film was written and directed by Volker Schlondorff. It will be shown with English subtitles.

“Ju Dou,” the controversial film that came out of China last year, will be presented Sunday by the Ojai Film Society. The movie was nominated for an Academy Award for best foreign film, the first such honor given to a Chinese production.

It is a story of passion, adultery and revenge that didn’t exactly please the Chinese government. After the movie was submitted for an Academy Award, the government tried to pull it out of the competition.

The film will be shown at the Ojai Playhouse beginning at 4:30 p.m. The playhouse is at 145 E. Ojai Ave. For information, call 646-8946.
