Viewers and critics always have their personal favourites, but some films achieve a masterpiece status that becomes unanimously agreed upon – something that's undoubtedly true of Andrei Rublev, even though it's a film that people often feel they don't, or won't get. It is 205 minutes long (in its fullest version), in Russian, and in black and white. Few characters are clearly identified, little actually happens, and what does happen isn't necessarily in chronological order. Its subject is a 15th-century icon painter and national hero, yet we never see him paint, nor does he do anything heroic. In many of the film's episodes, he is not present at all, and in the latter stages, he takes a vow of silence. But in a sense, there is nothing to "get" about Andrei Rublev. It is not a film that needs to be processed or even understood, only experienced and wondered at.
From the first scene, following the flight of a rudimentary hot air balloon, we're whisked away by silken camera moves and stark compositions to a time and place where we're no less confused, amazed or terrified than Rublev himself. For the next three hours, we're down in the muck and chaos of medieval Russia, carried along on the tide of history through gruesome Tartar raids, bizarre pagan rituals, famine, torture and physical hardship. We experience life on every scale, from raindrops falling on a river to armies ransacking a town, often within the same, unbroken shot.
With Andrei Rublev, Tarkovsky was consciously crafting a language that owed nothing to literature, and it's a pity so few others followed him. In today's cinema, we're still served up linear, cause-and-effect biographies of artists as if, by doing so, we'll understand the person and be able to make sense of their art. Andrei Rublev operates according to a different understanding of time and history. It asks questions about the relationship between the artist, their society and their spiritual beliefs and doesn't seek to answer them. "In cinema it is necessary not to explain, but to act upon the viewer's feelings, and the emotion which is awoken is what provokes thought," wrote Tarkovsky in 1962.
Despite its apparent formlessness, Andrei Rublev is precisely structured and entirely aesthetically coherent. Acts of creation are mirrored by acts of destruction, there are themes of flight, of vision, of presence and absence; the more you look, the more you see. And then there are the horses, Tarkovsky's perennial favourite: horses rolling over, horses charging into battle, swimming in the river, falling down stairs, dragging men out of churches. At times the screen resembles a vast Brueghel painting come to life, or a medieval tapestry unrolling. We're always conscious of life spilling out beyond the frame, and never conscious of the fact that this was made in 60s USSR. In Tarkovsky's own turbulent time, the film lit all manner of controversy. Its Christian spiritualism offended the Soviet authorities; its depiction of Russia's savage history upset nationalists like Aleksandr Solzhenitsyn, and its challenging form led to various cuts. After opening in Moscow in 1966, it was suppressed until the 1969 Cannes film festival, and didn't reach Britain till 1973.
We don't necessarily know, or need to know, how Andrei Rublev works or what it's telling us, but by the end we're in no doubt it's succeeded. When in the final minutes, the film pulls off its most famous flourish: the screen bursts into colour and we're finally ready to see Rublev's paintings in extreme close-up – coming at the end of this epic journey, they can reduce a viewer to tears. As the camera pores over the details, the tiny jewels on the hem of a robe, the lines forming a pitiful expression on the face of an angel, the tarnished gilding of a halo, we feel like we understand everything that's gone into every brushstroke. We're reminded of what beauty is. It is as close to transcendence as cinema gets.
