Noble stars Irish actress Deirdre O’Kane in the title role and was shot last year in Vietnam and Liverpool.
It will be screened for the first time at the Santa Barbara International Film Festival, California, which kicks off on Jan 30.
The movie’s producers will be hoping to impress a string of top Hollywood names who are due to attend the 11-day festival.
Stars attending the event will include Leonardo di Caprio, Martin Scorsese, Robert Redford, Oprah Winfrey, Cate Blanchett, Emma Thompson, and Forest Whitaker.
The film charts the 69-year-old award-winning charity worker’s incredible life, beginning from her impoverished childhood in Dublin, which included years spent homeless on the streets of the capital.
Over the past 23 years Christina is credited with transforming the lives of an estimated 700,000 street children in her adopted Vietnam and Mongolia through the Christina Noble Foundation.
The charity worker recently revealed how she relies on God’s guidance in her daily work.
The Dublin mother of three, who is a devout Catholic, said her religion was forged during her impoverished childhood, many years of which she spent fending for herself on the streets when “God was my only companion”.
She said: “I’ve always had a strong faith, exactly what I had when I was a child, because it’s all I ever had,” she said.
“And whenever I’ve been in trouble or needed answers to something, God always helped me.
“I feel very fortunate to have that, because it’s given me a great sense of peace.
“I still go to Mass sometimes, but mostly I just have conversations with God and that happens every day.
“If I’m worried about something and can’t sleep, I’ll ask for help and when I wake up I know where to go.”
