In a Friday morning tweet, Reynolds shared an edited version of the poster for "Joker" that read: "YOU MOTHER F---ER."
On an image of the movie's star, Joaquin Phoenix, was a list of eight other characters from high-grossing films. The list included Deadpool, Neo from "The Matrix," Pennywise from "It" and Jesus from "The Passion of Christ," among others.
Reynolds, who recently celebrated his 43rd birthday, also said: "R-Rated box office congratulatory posts aren’t like the ones you’re used to..."
In 2016, "Deadpool" grossed about $783 million and the sequel earned $738 million before a PG-13 re-release brought the film up to $785 million.
So far, "Joker" has pulled in more than $788 million and is expected to hit $800 million over the weekend and grow even further as its theatrical release continues.
