I've recently found this updated short movie on Cao Dai by Richard Van Lê, which fits my current mindset, as I am thinking of a photo expedition-workshop to Vietnam in the near future.
Cao Dai (Cao Đài) is a syncretistic, monotheistic religion, officially established in the city of Tay Ninh, in southern Vietnam, in 1926. Its first disciples claimed to have received direct communications from God, who gave them explicit instructions for establishing a new religion. It's a blend of elements from Buddhism, Taoism, Christianity, Confucianism, Hinduism, Islam, and Animism.
Its saints' list is rather an eclectic one; with Buddha, Confucius, Victor Hugo, Joan of Arc, William Shakespeare, Victor Hugo, Louis Pasteur, and Jesus.
More background on Cao Dai can be found here.
