The Princess Bride (1987)

"Have you ever heard of Plato, Aristotle, Socrates?"

"Yes."

"Morons."

It's a genuine mystery: This Is Spinal Tap is one of the funniest films ever. How, then, can pretty much the same team- Rob Reiner directs, Christopher Guest has a major role- produce something so unfunny as this.

I can see what it’s trying to do- play with the silliness of the tropes and cliches. Hence we have exaggerated tropes such as a princess with absurd faith that her ridiculously heroic man will save her, and a Spanish swordsman who lives to avenge his father’s death. But none of this is addressed with any real wit, and it’s obly the names (Prince Humperdinck) and cameos from the likes of Peter Cook and Mel Smith that tell us this is intended to be a comedy.

All this is narrated by Columbo to his annoying, sport-obsessed grandson for no apparent reason, in a framing sequence that has no obvious reason to be there. It describes a weird mediaeval word where fictional countries mix with real ones and people seem to have heard of Australia. And where there are, er, “rodents of unusual size” which look awfully like a man in a suit. It’s clearly meant to be funny. It isn’t. An odd misfire.

I very strongly suspect, mind, that the “battle of wits” scene strongly influenced the first episode of Sherlock.
