I’ve sometimes found the surreal, satirical and sometimes plain silly humour of the Monty Python troupe hit-and-miss. But when it lands, it really lands and Monty Python and the Holy Grail may well just be their finest hour. Essentially a series of sketches loosely worked together into a sort-of-plot, but never taking itself too seriously, it’s an often-inspired collection of highly influential gags delivered by a troupe of performers at the top-of-their-game (it’s hard to believe that they have all said shooting the film was a tough, punishing and exhausting process).

What Python got right here is how easy – and hilarious – it is to poke fun at something so very po-faced and serious as medievalism had a tendency to take itself back then. In fact, it’s perhaps a lasting tribute to the film that no-one has ever been able to take it quite as seriously since. Monty Python and the Holy Grail also lines up shots at the arthouse high-brow seriousness of films like Andrei Rublev and, most famously, The Seventh Seal (those hilarious, moose-obsessed, opening credits are a flawless take-down of Bergman’s portentous opening) but also a dismantling of the likes of Bresson’s Lancelot du Lac (no-one can watch that film’s opening now without picturing the Black Knight protesting ‘It’s a only a flesh wound!’ as crimson spray flows freely).

I love Holy Grail. It’s practically designed for undergraduates to sit around and watch, while getting slowly pissed and then spend ages quoting at each other. Many of its jokes lean into bizarre surrealism and funny sounding words – “shrubbery!” just sounds funny, even more so when it’s squeaked out by a giant Michael Palin in a ridiculous helmet affecting a rhotacism. And the Pythons knew how to turn problems into genre-defining gags: thank God they couldn’t afford horses, so instead came up with the frankly genius idea to just mime the knights riding horses to the sound of two coconut halves being visibly tapped together by their squires.

And then to have the comic presence of mind to riff on enforced ideas like this so much (just how did coconuts turn up in medieval Britain?) that for generations, fans will ram their tongues earnestly into their cheeks debating the migratory habits and air speeds of laden and unladen swallows. It’s all part of a superbly written script, which get just the right balance between Thomas Mallory-esque medieval rhythms laced with nonsese ( “The swallow may fly south with the sun or the house martin or the plover may seek warmer climes in winter, yet these are not strangers to our land”) and a mix of anachronistic casualism and simmering middle-class frustration. All the time in Monty Python and the Holy Grail there are traces of the sort of serious, played-dead-straight, medieval film this could be, making the constant punctuation of surreal, fourth-wall leaning, silliness all the more hilarious.

A lot of this also comes down the highly skilled comic playing of the troupe. Graham Chapman, in particular, has the seemingly dull job of playing the straight-man. But his ability to play, even the most ridiculous encounters, with complete earnestness is crucial to the film’s success. Arthur is, really, a ludicrous figure, but Chapman knows he can never acknowledge this for the joke to work. Hilariously, the legendary king here becomes a sort of put-upon middle-manager, constantly frustrated while going about his day job, dumb enough to be unaware of how absurd he is, but smart enough to get frustrated at the increasingly dim antics of his followers.

It also allows the rest of the troupe to let rip with broader comic performances, all of whom have a whale of a time. John Cleese’s pompous bossiness and control-freak mania is perfect for the psychotic Sir Lancelot while his latent comic cruelty, combined with a passion for silly accents and walking, is perfect for the famed French taunter (the funniest Frenchman on screen). Palin’s goodie-two-shoes decency is great for the tempted Sir Galahad while his brilliant capacity for deluded self-importance nails the Lord of Swamp Castle – and who else could have taken such an impish delight in the Trotskyist mantras of the socialist peasant Dennis? For the rest of the troupe, Eric Idle’s mix of cheek, dressed-up poshness and wimpy weakness is expertly used while Terry Jones mocks academia as Sir Bedevere and whines brilliantly as Herbert. And no-one does dirty better than Terry Gilliam.

Gilliam and Jones also directed, allegedly not always harmoniously neither quite agreeing if this was a film or whether it was a comic show. But the presence of Gilliam behind the camera probably accounts for why this is the most visually striking Monty Python film, with mists rolling over the hills and the Scottish locations given a mythic power which makes the silly jokes that happen all around them even funnier – while Jones’ medievalist background surely helped define the film’s surprisingly authentic (and therefore even funnier) feel. Holy Grail also very successfully disguises that it was effectively all shot in one or two locations (Doune Castle is shot from so many angles it becomes about a dozen different locations).

But what really makes Holy Grail work is the quality of the jokes. And it opens with a run of gags of such consistent quality they are perhaps unparalleled in Python’s work. The Swallow debate. Bring Out Your Dead. Peasants nailing the ‘self-perpetuating autocracy’. The flesh wounds of the Black Knight. The witch trial. The French Taunter (“Your mother was a hamster and your father smelled of elderberries!”). The Trojan Rabbit. Camelot being a silly place. The opening half of the film is one piece of solid comic gold and if the second half doesn’t have quite the same hit rate, it’s still more than funny enough.

And funny is what it is all about. You can say ‘it doesn’t have as good a plot as Life of Brian’. You can say it just ends, as if the troupe ran out of ideas. You can say it loses a steam. But it doesn’t matter when you laugh and laugh time and time again at its best bits. And you really do. And people who encounter it at the right age, will go on laughing at it for the rest of their lives., for decades to come.
