The two actors have had many public fallouts over the years since they starred together in the 1987 psychological horror Angel Heart, when Rourke claimed De Niro declined to talk to him on set because of the complicated relationship between their characters in the film.
On Friday (17 July), Rourke referred back to one of their more recent arguments that began last year when he claimed that he lost out on a role in Martin Scorsese’s The Irishman because De Niro refused to work with him.
De Niro's representatives released a statement at the time, saying Rourke was “never asked to be in The Irishman nor was he ever even thought of, discussed or considered to be in the movie”.
“Hey Robert De Niro, that’s right I am talking to you, you big f***ing cry-baby,” wrote Rourke, 67, in the new Instagram post.
“A friend of mine just recently told me that a few months back you're quoted as saying to newspapers ‘Mickey Rourke’s a liar he talks all kind of s***.’
“Listen Mr.Tough Guy in the movies, you're the 1st person that ever called me a liar and it was in a newspaper.
“Let me tell you something, you punk a**, when I see you I swear to God on my Grandmother, on my brother and all my dogs, I gonna embarrass you severally 100%.”
