Why are Judaism & Islam never mocked or impugned in mainstream movies?

For the purposes of this thread, I’d say that they do. By having both likable and unlikable Christian characters, the film establishes that likablilty and unlikability are traits independent of Christianity. These characters aren’t impugning Christianity, they’re just antagonists who happen to be Christian. You are effectively arguing that any movie that does not present Christians as flawless is automatically impugning Christianity. Which makes it impossible to make a good Christian movie, as Christian philosophy hinges on the idea that everyone is inherently flawed.

Anglicans stereotypically lisp? Come on. And what makes you think he was meant to be Anglican rather than Catholic? Since The Princess Bride was explicitly NOT set in England it wouldn’t make much sense to have the priest be CoE.

The fictional kingdom name of “Florin” evokes Florence, Italy and the florin coin that was its currency. Italy is a predominantly Catholic country. The other book Goldman wrote under the name of the fictional Florinese author S. Morgenstern (The Silent Gondoliers) is set in Venice, further suggesting a link between Florin and Italy.

I seem to recall that the Friar in the Costner Robin Hood joked about being drunk on sacramental wine. Rewatching the movie to confirm this is, however, a sacrifice I am unwilling to make for the sake of this thread.

The Princess Bride is a fairy tale, not an historical document. Like all fairy tales, it’s supposed to represent something contemporary even though it’s set in the distant past. Sorry if a tedious, lisping, marbles-in-the mouth English cleric sounds like a reach for you.

Just remember Alan Rickman’s in it. And he’s awesome. “Because it’s dull, you twit! It’ll hurt more!”

And his rape scene is hi-larious!

I think I’ll pass.

And you think that “something contemporary” is Anglican bishops? Again, come on.

I am totally unfamiliar with any such stereotype of English clerics. As an American I might simply be ignorant of them, but so would most of the film’s target audience. Since the author of both the novel and the screenplay is a Jew from Chicago I somehow doubt he’d be familiar with or have reason to want to spoof the stereotypical foibles of Church of England clergymen either. The scene definitely wasn’t improvised by Peter Cook for the film, as it appears almost verbatim, complete with speech impediment, in the original novel (published 15 years before the movie was made).

So yeah, I have to say it sounds like something of a reach. But even if you’re right and William Goldman did for some reason want to poke fun at these supposedly stereotypical speech patterns of CoE clergy, that 1) has nothing to do with any Christian belief or ritual and 2) is balanced by the stereotypically Jewish speech patterns of Miracle Max and Valerie. So The Princess Bride is, at worst, quite evenhanded in the way it deals with religious-linked cultural stereotypes.

Judging from my own film-watching experience the examples people have been able to come up with in this thread, it seems clear enough to me that Christianity is very rarely the butt of jokes or derision in mainstream Hollywood films, Judaism is rarely attacked but is often the subject of humor, and Islam is rarely joked about but is nearly always portrayed in a very negative manner. The OP had things completely backwards.
