The troubled actor's new war thriller Man Down earned just ??7 ($11.50) at the UK box office during its theatrical opening this weekend, Variety reports.

That's the equivalent of one sold cinema ticket.

"Poor Shia, that opening could be in the Guinness World Records or something," a senior media analyst at data company ComScore told the trade magazine.

Of course, there's context. The film, which was simultaneously released digitally for download and streaming, opened in just one cinema in Burnley.

But even that doesn't excuse its dismal pull: The Void, a Canadian horror movie starring Ellen Wong, also opened in just one cinema this weekend and took in ??1613 ($2650), according to The Independent.

Man Down, a thriller set amidst the war in Afghanistan, also stars Sydney actor Jai Courtney (Suicide Squad) and Oscar nominee Gary Oldman. It reunited LaBeouf with Dino Montiel, the director of his 2006 indie breakthrough A Guide To Recognising Your Saints.

The film was released in the US in December last year where it grossed $US454,490 ($600,530), following an opening run at the 2015 Venice Film Festival.

"The script landed on my lap at just the right time - [Montiel] came to my house when I was at a really low place and offered it to me like therapy, like, 'Here's a healing process where we can jump into together and get well,'" LaBeouf said about the film at Venice.

But negative reviews - the film has a Rotten Tomatoes score of just 15 - saw its theatrical run largely shelved internationally.

While Variety notes a potential "silver lining", saying media headlines over the film's tiny grosses may boost the small project's profile, it's another dent on LaBeouf's floundering reputation.

Once a bankable box office topper in Hollywood blockbusters like Steven Spielberg's Indiana Jones and the Kingdom of the Crystal Skull and Michael Bay's Transformers franchise, the star has earned more attention for his off-set shenanigans than his work in recent years, including a recent scuffle that saw him arrested for assaulting a Nazi sympathiser at his anti-Trump art installation in New York City.

The actor, who did earn raves for last year's festival fave American Honey, will next be seen playing John McEnroe in a Scandinavian production that follows the tennis great's '80s rivalry with Swede Bjorn Borg.
