Michael Shannon had been widely rumored to be the top pick for the Deadpool co-star.
“Deadpool” became a breakout hit in 2016, grossing over $783 million worldwide. The irreverent and very R-rated comic book film even became an unlikely awards contender late in the game with two Golden Globe nominations and a Directors Guild of America Award nomination for Tim Miller.
David Leitch is directing the sequel, which is expected to hit theaters sometime in 2018.
