Shah Rukh Khan, the top movie star in India and one of the top stars in the world, is filming his new movie in Alabama this month, producers say.

Production began this week in Huntsville of the film "Zero" starring Khan and Indian actresses Katrina Kaif and Anushka Sharma. Crews have filmed at Grille 29, the Huntsville Botanical Garden and the Hindu Cultural Center of Alabama in Harvest.

Film co-producer Karuna Badwal, who is also Khan's business manager, talked about the project Thursday at the Hindu Cultural Center of North Alabama outside Huntsville, where several dozen actors and locals were dressed in traditional Indian clothes for a temple scene.

Badwal would not discuss the film's plot in detail, but she said some scenes will be filmed at the U.S. Space & Rocket Center. The film will be the most expensive Indian movie ever made, she said, partly because of the technical equipment the plot requires. Producers have brought 90 people from India to Huntsville and hired another 50 from American production companies, Badwal said.

Prashant Shah, U.S. executive producer for the film, worked with the Alabama Film Office and the U.S. Space & Rocket Center to arrange production of the film in Huntsville.

Friday's filming was of a wedding blessing from a priest to a couple engaged to be married. The cast went through several takes while visitors, including U.S. Space & Rocket Center CEO Dr. Deborah Barnhart, watched from the back of the temple.

Khan has not arrived in Huntsville, and producers won't say when he will arrive or how long he will be in the city. Known in India and around the world as SRK, Khan has appeared in more than 80 films. He is the co-owner of his own film production company and has won awards for his support for children's education and for women's and children's rights in India.

Hindu center President Rashpal Thakur said having a movie shot at the center "is a new experience," but he said it was "a very thrilling experience to share our religion and culture."

The Huntsville area has a large Indian and Indian-American community with many members employed by the city's aerospace and defense industries. Thakur said the center has 1,000 families on its roles with about 500 active at any given time.
