Michael Caine’s Harry Palmer meets his nemesis in director Ken Russell.
By the time Billion Dollar Brain rolls around, Harry Palmer has traded in grey bureaucracy and peeling filing cabinets for something altogether more outlandish: fascist supercomputers, frozen Finland, and a Texan oilman with delusions of geopolitical grandeur. It’s the moment the Palmer films stop muttering under their breath and start yelling into the wind, but somehow, Caine keeps it anchored with a raised eyebrow and a permanently lowered enthusiasm threshold.
This third outing abandons the queasy realism of The Ipcress File and the double-dealing precision of Funeral in Berlin in favour of something more grandiose and unstable. Directed by the ever-unpredictable Ken Russell, Billion Dollar Brain flirts with camp, flings itself into surrealism, and occasionally forgets it’s supposed to be a Cold War thriller at all. And yet, it isn’t a betrayal of what came before. If Palmer’s previous adventures charted the disillusionment of a man stuck in the dull machinery of state, this one shows what happens when the machinery gets hijacked by a lunatic with a God complex and an IBM mainframe.
It could be argued that Billion Dollar Brain sees Palmer give up fighting the good fight and capitulating – stylistically at least – to Bond’s all-conquering glamourisation of statecraft. The lunatic Texan, the ice-bound set pieces, the villain with a supercomputer and a private army: these are the fever dreams of a spy franchise absorbed into the mythology it once mocked. But crucially, Palmer himself doesn’t change to fit the mould. He’s dragged into the circus, but never joins the parade. His body’s in a Bond film, but his soul’s still sat in a smoky office in Whitehall, muttering about expenses forms. That weary detachment becomes the film’s anchor.
Palmer, now freelancing, is pulled back into the world of espionage when a mysterious voice on the phone assigns him a courier mission. The trail leads him to Texas, Latvia, and finally the snow-covered edges of Soviet Europe, where he uncovers a mad scheme by General Midwinter (Ed Begley), a wealthy American anti-communist zealot with a private army and, yes, a billion-dollar computer to manage his global operation. It’s what Bond villains dream of while drunk.
What makes it work – at least in fits and starts – is that Palmer still refuses to be impressed. He reacts to Midwinter’s rants, the high-tech paranoia, and the florid villainy with the same weary disbelief he brought to interdepartmental memos and office tea rotas. He’s the only grown-up in a room full of lunatics, and Caine plays it like Palmer’s primary spy skill is simply not buying the hype.
Ken Russell is not Sidney J Furie or Guy Hamilton, and Billion Dollar Brain isn’t interested in subtlety. It’s interested in scale, in strange tonal swings, in framing Palmer against cracked ice and cracked ideology. There are moments of visual bravado – the frozen lake standoff is both ludicrous and breathtaking – but also whole stretches where narrative coherence takes a tea break. Yet even when the story frays, the character work just about holds.
The supporting cast plays to the film’s extremes. Karl Malden’s Leo Newbigen, Palmer’s morally flexible acquaintance, brings a sleazy charm that plays nicely off Caine’s guarded exasperation. Françoise Dorléac adds some glamour as the enigmatic Anya, though her role is more cipher than fully developed character. Ed Begley’s Midwinter is a fever-dream caricature of American Cold War hysteria – imagine Slim Pickens with a budget and fewer brakes.
It’s less faithful to Len Deighton’s original tone than the earlier films, but the bones of the story are still rooted in Deighton’s blend of cynicism and spy craft. What Russell adds is operatic absurdity, pushing the series to a stylistic extreme that few other spy films have dared to match. It feels more like a tangent than a continuation, but it’s a bold, deranged, and occasionally brilliant one.
Billion Dollar Brain may be the most divisive of the Palmer films, but it earns its place by showing just how far the series could stretch without snapping entirely. It may not be subtle, or even especially coherent at times, but it still understands the essential appeal of Harry Palmer: a man adrift in the nonsense of geopolitics, making eggs, dodging bullets, and keeping his sarcasm sharp enough to cut through ideology, dogma, and now, Texas-sized megalomania.
