This paper examines how the film s public screening of the novel Ayat-ayat Cinta shapes an indonesian Muslim public sphere in which the notion of religious authority is re-created. It operates on three levels first the audiences perception of the film as a da wah and their reactions toward the film s content second the rivalry between the novel writer and the film director on particular issues distancing the film from its novel version and third the public debates on the issue of polygamy revealed by the film. The paper finds out that the film Ayat-ayat Cinta has arguably invited muslim people to have their religious teaching in cinema. More importantly the wide publication of the film on the internet and mass media has anabled all individuals to take part in the debates raised by the film. In these debates participation is widely open to all and argumentation is not based on superiority.
