For those few that don't already know, “Breaking Bad” was a highly successful and popular TV series on AMC, which ran over five seasons, beginning in 2008 and ending on 2013. Following this in 2015, “Better Call Saul,” an equally popular spin-off series, started which is still building in fame, reintroducing so many of fans’ most popular characters.

Now the two main actors of “Breaking Bad” – Bryan Cranston and Aaron Paul – have sent out cryptic tweets, hinting that there is a reunion on the way for their two characters, something that has been teased for quite some time.

‘Drug mule’ tweets excite fans

As reported by Metro, on Tuesday, 25 June, two identical tweets were sent out at the exact same moment (7:02 pm). One from the account of Bryan Cranston, @BryanCranston and the second from @aaronpaul_8. The tweets included an image of two friendly mules and the cryptic word “soon.” View the two tweets here.

The film adaptation of ‘Breaking Bad’

Looking back to last year, The Hollywood Reporter ran a story on 7 November to announce that “Breaking Bad’s” creator, Aidan Gilligan, was busy working on a two-hour Film adaptation of the original show.

Sources said at the time that the film - with a working title of “Greenbrier” – would be set within the existing “Breaking Bad” franchise. A brief synopsis revealed that the story would follow the escape of a kidnapped man, along with his quest for freedom.

According to NME, Bryon Cranston had also confirmed the fact that a “Breaking Bad” movie was on the way, but at the time he wasn’t sure if his character, Walter White, would be in the film, especially as that character died at the end of the final season of the show.

Cranston said he had yet to see a script for the film but had reportedly spoken to Gilligan about it. He told radio host Dan Patrick there was a question as to whether Walter would be in the film, but with the latest tweets, they have certainly got fans wondering.

Gilligan and ‘Better Call Saul’ executive producers involved

So far everything is still pretty much up in the air and it is unknown whether the movie would be a sequel or prequel to the original “Breaking Bad” series.

It is also unclear whether the original stars would be involved in the film.

However, according to sources, Gilligan will be writing, executive producing and possibly even directing the spin-off film, while Melissa Bernstein and Mark Johnson – executive producers for “Better Call Saul” – have also been linked with the film project. NME notes that Gilligan revealed last year that he wanted “desperately” to have a reunion between Walter White and Jesse Pinkman on “Better Call Saul,” so maybe the tweet is about that possibility? Fans will have to wait and see for now.
