Shia LaBeouf's pulled some pretty strange stunts in his time, with his days as a mop-haired teen in Disney show Even Stevens and 2003 flick Holes fading into distant memories.
He's done everything from wearing a paper bag over his head to the prestigious Cannes Film Festival to setting up a live stream of his heartbeat, all for the sake of his art - or perhaps just to cause a stir.
As part of his most overtly political work to date, LaBeouf and collaborators Nastja Säde Rönkkö and Luke Turner set up a public art campaign called #HEWILLNOTDIVIDEUS, in response to Donald Trump's presidency.
The project, which invited people to recite the phrase 'He will not divide us' repeatedly, drew the crowds thick and fast - including one man that LaBeouf allegedly assaulted.
Well, it also turns out that the actor's had a bit of controversy surrounding the pretty tankin' Tom Hardy - who LaBeouf reportedly knocked out.
According to Esquire, the British Peaky Blinders and Dunkirk star was decked by LaBeouf on the set of 2012 movie Lawless.
"He dove headfirst into the deep end of character prep, blurring the line between acting and reality," Esquire's Eric Sullivan writer.
"While filming Lawless, he drank moonshine by the gallon, carved a message from his character into the door of Mia Wasikowska's hotel room, and knocked out Tom Hardy."
Sullivan adds: "On the set of 2013's Charlie Countryman, he dropped acid and choked the director when he tried to break for lunch."
However, apparently Hardy has since admitted he has nothing but respect for his controversial co-star - explaining that such erratic behaviour is just one of the paradoxical, occupational hazards that actors face.
"A performer is asked to do two things: to be disciplined and accountable, communicative and a pleasure to work with," Hardy told Esquire.
"And then, within a split second, they're asked to be a psychopath. Authentically.
"It takes a very strong human being to sustain a genuine sense of well-being through that baptism of fire," he added. "Drama is not known to attract stable types."
The two worked together on crime film Lawless, which told the violent tale of three bootlegging brothers and the men who try to shut down their prohibition-era moonshine business.
LaBeouf is now set to star in forthcoming adventure flick The Peanut Butter Falcon, while Hardy's highly anticipated Venom is due to hit screens later this year.
