Arnold Schwarzenegger sent fans wild as he reunited with Twins co-star Danny DeVito for his latest post on Instagram - which bizarrely featured former Prime Minister Tony Blair. 

Schwarzenegger and DeVito, 77 and 80, starred in the 1988 film with the former playing the streetwise Vincent and the latter cast as his twin, the intelligent but naive Julius. 

The movie was iconic, grossing more than $216million and marking Schwarzenegger's first stab at a comedic role alongside acting royalty DeVito. 

So fans were understandably excited to see the duo had reunited for a photo on Arnold's Instagram on Monday, with the post racking up more than 200,000 likes in a matter of hours. 

The picture showed the actors stood either side of British politician Tony Blair, 71, with the trio all cracking beaming smiles as they stood arm-in-arm next to a swimming pool.

'I love bringing old friends back together,' Schwarzenegger's caption gushed. 

'It was fantastic to see my dear friend Tony Blair and introduce him to my brother, @dannydevito. 

'I can't wait to talk about termination pollution together in Vienna at the @schwarzeneggerclimate summit!'

Film fanatics were quick to take to the comments section to express their excitement at Schwarzenegger and DeVito's link-up, though some called Blair's inclusion 'random'.

One commented: 'All legends in their own right!'

'These three together looks like the start of an Always Sunny in Philadelphia episode,' quipped another.'

While one more simply wrote: 'This has got to be the most random link-up ever.'   

Schwarzenegger and Blair actually collaborated during the actor's time as Governor of California, nevertheless.

In fact, the governor was Blair's final guest during his time as PM when he visited Downing Street in 2007. 

The pair had met to discuss climate issues and low-carbon economies - environmental issues which Schwarzenegger has been vocal about. 

And Blair and Schwarzenegger's meeting, alongside DeVito, comes a few weeks before they will all discuss climate issues at the actor's ninth annual conference in June. 

Only last year, the iconic acting duo sent fans into a frenzy when they reunited onstage at the Oscars more than 30 years after the release of Twins. 

Schwarzenegger and DeVito took to the stage in March 2024 to present the award for best visual effects of the year, which was handed to Godzilla: Minus One. 

Just a matter of days after their reunion at the Oscars, film fanatics' excitement was compounded when DeVito revealed that he and his former co-star may have another film in the works. 

Speaking to Fox News, he said: 'Mr Schwarzenegger, he's like my buddy, we're trying to do another movie together.

'There's a script being written, we're working with Warner Brothers right now, we want to get back on the big screen together.

'It won't be a sequel, Ivan [Reitman who directed Twins] is no longer with us. I knew Arnold before twins, I'd see him once in a while, we're looking forward to getting back on the screen together.

'So next year, fingers crossed, we'll be back in production with something We always have a good time together, he's a sweet guy.'

There is yet to be any further updates on a potential new movie, however. 

The 1988 film Twins saw the duo portraying genetically engineered siblings who only crossed paths when they reached adulthood.  

The iconic stars were involved in a long-in-the-works sequel to Twins called Triplets, where the brothers would discover that they're actually triplets.

There were reports suggesting Eddie Murphy would be joining the cast of the sequel, and Tracy Morgan was even reportedly set to take on a new role in the film. 

However, the project was put on hold after the original film's director, Ivan Reitman, passed away at the age of 75 in February 2022.

Ivan's son and Hollywood heavyweight director, Jason Reitman, was then pitched the film but, according to Schwarzenegger, he was the one to give it the red light.

The only other time Schwarzenegger and DeVito had appeared together on-screen was for the 1994 film, Junior.
