The representation of Judas gives, along ages, a good understanding of the mind of Christianism wrote KIERKEGAARD. Through the religious and political study of 121 films released from 1897 to 2020 we discover the apostle portrayed as an arch-villain but also as a tragic hero, a victim, even sanctified. Judas' fair treatment, his hagiography or his accusation is a touchstone of the theology of the movie director and of the production companies. We analyze for each film its respect for the Scriptures and qualify its message either ecumenic or anti-Semitic.
