A large-scale film project has launched today across western Sydney exploring the personal and daily practices of various people of faith.

The One Day for Peace documentary film by the Urban Theatre Project tells the stories of 27 people of various religious backgrounds with the aim of starting conversations around the role of faith in the public space.

The film will be screened outdoors on large projectors across seven locations in western Sydney including Parramatta Town Hall, Liverpool Library, Auburn Central and Blacktown Train Station.

Urban Theatre Project artistic director Rosie Dennis said the film aimed to challenge stereotypes and showcase the big role religion played in western Sydney.

"We want to tell a different story, we think western Sydney is incredibly dynamic and really interesting," she said.

"Four out of five people identify as being connected to an organised religion in western Sydney.

"In Australia we don't talk about religion, I think that's got to change."

Ms Dennis said it was a deliberate strategy to place the film in locations with high pedestrian traffic.

"We want to start a conversation and intersect with people's every day," she said.

"Just by placing it in the public space, someone who might not know very much about Sikhism or Islam but has a particular perspective on Muslims then possibly they might see something in the documentary that they didn't know before."

Participants say the film tackles judgment

Revesby father and son Padam and Gursagar Singh both took part in the film project to share their personal faith of Sikhism.

Businessman Padam Singh said as a practicing Sikh he maintained a meditative state of mind and performed daily prayers and songs.

"During the daytime also, a Sikh is supposed to have a meditative state of mind," he said.

"Some of us rise at 2:00am or 3:00am in the morning, do an hour of meditative chant, of God's name, then we read the scriptures, the five morning prayer scriptures.

"Then we have our holy book of Sikhs, we do the opening of the book and we take the verse for the day, we also sing, it's all in poetry."

University student Gursagar, 21, who wears a traditional turban, said the film was an educational tool.

"It's better people understand what it means, that ignorance only leads to hate," he said.

"This project reveals the true meaning behind what every religion is.

"When that educates people, they'll realise these people are just like us, they just want to live peacefully."

Silverwater Muslim resident Tehara Chaudrary and her three children talk in the film about the physical benefits of praying five times a day.

"I pray five times a day, I fast, I stay healthy and I stay connected to God," she said.

"For me Islam is a complete way of life not only for myself but for the community."

The 46-year-old Indian mother of three said the film would encourage people to avoid judgment.

"We should know what each religion is about and read their book," she said.

"Before we judge or come to conclusions, we should look deeply at others."

The film will be played from 6:00 to 7:00pm weeknights from September 14 to 27.
