The Expendables 4 is an upcoming action film and is a sequel to the 2014 film, The Expendables 3 and the fourth installment of the franchise.
In a November 2013 interview, Couture confirmed that filming had finished on the third film, and that discussions for a fourth Expendables film were taking place.
In May of 2014, various media cited how Stallone actually was on good terms with Bruce Willis via Twitter comments and interviews. He acknowledged that it had sounded like a hostile breakup but actually had just been a schedule that hadn't worked out, which was why Willis didn't return and Harrison Ford was in the third film.  Fans and other sites later started speculating if this meant that Willis would return in the fourth film.
Throughout 2017, it was reported on the film being in development hell due to continual production difficulties. It began when Stallone almost exited after Stallone was failing to find common ground on the script with producer Avi Lerner and having found the success he desired returning to his Rocky role in the sequel Creed in 2015.  A sales poster was never-the-less shown on various Action movie sites and blogs by Millennium Films despite various reports already breaking out about Stallone's potential exit. 
On February of 2018, Terry Crews noted to media outlets and on his Twitter account a growing issue where he had finally come out to admit that a Hollywood agent had touched him appropriately at a party. He revealed that the agent just so happened to represent Stallone and implied that Lerner's reps were asking Crews to drop his lawsuit against Stallone's agent.  This lead to various speculation on wether or not Crews would return to the franchise. Crews had previously stated in 2016 he was interested in returning as long as Stallone was still involved. 
On May 16, 2018, Millennium Films also updated its promotion space at Cannes film festival by showing off posters for it's other film sequels Rambo V and Angel Has Fallen.  Further coverage was later documented days later.
