But did you know he was also in Star Wars? Well, kind of.
Because believe it or not, the actor played a stormtrooper in 2017's Star Wars: The Last Jedi.
The scene sees Finn (John Boyega), Rose (Kelly Marie Tran) and DJ (Benicio Del Toro) dressed as Imperial officers attempting to infiltrate the First Order.
Nervous enough as it is, Finn's worries are heightened when a familiar voice echoes behind him. The American-sounding stormtrooper seems to recognise him.
Worried that he's about to have to get all up in his grill/shoot him to death with lasers, Finn reaches for his gun, only to be stopped by DJ.
Thankfully, Hardy's Stormtrooper is just glad to see him (not like that, it would be painful in the Stormtrooper costume) and expresses surprise as he never had Finn down as 'captain material'.
He then slaps Finn (a superior officer) on the a**e, risking punishment both for breaching the Empire's strict private/officer code of conduct and for slapping someone on the a**e, which you're not allowed to do.
Watch the scene here:
Hardy had previously been cryptic about his involvement in the film.
Asked about the rumours by The Hollywood Reporter, he said: "I don't know if I can even say that. Where did you hear that?"
Told the internet was the source, he added: "Ah, the internet is a glorious web of deceit and misinformation, isn't it?"
To be honest, using the 44-year-old as an anonymous stormtrooper does feel like a waste.
If you like actually being able to see Hardy in films, then you can check him out in Venom: Let There Be Carnage, which was released on Friday (15 October).
Hardy returns as Eddie Brock, a journalist who plays host to the alien symbiote Venom, while Woody Harrelson plays titular villain Carnage.
We first saw Harrelson as Cletus Kasady, a prisoner who has his own symbiote buddy - called Carnage - at the end of the first film, which prepared everyone for the plot of the sequel.
Screenwriter Kelly Marcel paid tribute to Hardy for his role in helping to devise the script for the second film, explaining how he decided to get involved with the writing process.
She told Empire: "This is new for him, to get credit.
"But it's not new for him to be this involved. He's absolutely 100 percent committed to everything that he does."
She added: "He's married to Venom. He loves this character. He's very involved in what he thinks should happen.
"He doesn't get a pen and write. We spent months breaking the story together on FaceTime, riffing on ideas, seeing what worked, seeing what didn't.
"Then I took everything we spoke about and holed up somewhere for three months quietly, knocking out a script."
