I have a theory that religious films of the 50's and thereabouts were made deliberately boring in order to drive people out of the Church, ha ha. Has anyone seen King of Kings? Christ is portrayed as having the charisma of a block of wood, he just stands there and lectures in a monotone. It would take a great deal of imagination to make a film that has so little imagination. You literally could not be more boring if you tried. Yet the director, Nicolas Ray, made many trashy films that were entertaining.
Easily the best Christ film in terms of artistic style is Last Temptation of Christ by Martin Scorsese. The lighting and the editing is state of the art, the images evoke lots of good religious art from the past. The problem is that it's blasphemous and heretical.
Mel Gibson's Christ film, from what I have seen, has trashy Titanic-style hard-edged lighting and THX sound effects, which are totally inappropriate for the life of Christ. I developed a prejudice to this film early on, I'll admit, so I'd better watch it before I say anything else.
There are lots of films made about Joan of Arc. Don't get excited. This is in order to push rebellion and feminism to girls. Unless you think girls watching these films will be able to understand that Joan of Arc wore men's clothes for special reasons and based on divine inspiration. Or that they will comprehend that Joan being burned was an act of an English cleric that was probably politically motivated, rather than an act of the mean, macho, masculine Church itself.
But of course, the historical context is blurred over or misunderstood, and all that people take away from Joan of Arc films is a sliver of a girl standing up for her right to be a soldier on the battlefield, and then persecuted by some Inquisition-like court. It makes it look like she is standing all alone against men, and against the unfair and unjust Church itself. Bleh.
St. Francis, also, is turned pretty much into Doctor Doolittle crossed with a hippie, a forerunner of Vatican II, in certain works of art ( Brother Sun, Sister Moon by Zefferelli, which is scored with songs of Donovan! )
