An action movie described as a mix of John Wick and Rambo is on TV tonight

It's got a 94% score on Rotten Tomatoes

Set in late 1944 during the Lapland War in Finland, the film follows a solitary prospector (Jorma Tommila) who crosses paths with Nazis on a scorched-earth retreat.

When the soldiers decide to steal his gold, they quickly discover that the seemingly ordinary miner is actually a legendary ex-commando.

"And no matter what the Nazis throw at him, the one-man death squad will go to outrageous lengths to get his gold back -- even if it means killing every last Nazi in his path," the plot synopsis reads.

Released in cinemas in Ireland and the UK in May 2023, the Finnish flick was a hit both at the box office and with critics, scoring 94% on Rotten Tomatoes.

It starts on Film4 tonight at 9.30pm.

In particular, critics singled out its mean-and-lean storytelling, its inventively gory action set-pieces and its atmospheric Lapland setting for praise.

Its sequel came out last year, too! Check out our review of the follow-up here.

You can also read a sample of some of the glowing praise for the original below:

Bloody Disgusting: "Sisu feels like a gritty actioner of yesteryear but with a modern sense of style. It’s a wild ride that begs to be seen with an energised crowd."

Empire: "Serving up stone-cold multiplex mayhem, Sisu makes no bones about it — this is a film about one mad bastard killing a gazillion Nazis. It’s almost impossible not to love it."

Globe and Mail: "If watching mass-murdering maniacs get absolutely destroyed on-screen is your thing – and it very much is mine – then Sisu is a perfectly depraved night out."

Observer (UK): "Sometimes all you want is a grizzled Finnish gold prospector relentlessly slaughtering cartoon evil Nazis in a variety of inventive and messy ways."

Ultimate Action Movie Club: "Part Rambo, part Wick, Sisu is the ultimate action saviour the modern genre needs."

Vulture: "I kept imagining it as what might have happened had Sergio Leone been alive to direct Crank: High Voltage."
