Constantine: City Of Demons was released in 2018. The movie was directed by Doug Murphy, and stars Matt Ryan, Laura Bailey, Robert Atkin Downs, and Damian O’Hare.
Although development hell seems to have claimed the long-hyped Gambit film (featuring Channing Tatum as the titular mutant hero), we now know one villain who was set to appear. Mister Sinister was set up in the end credits of X-Men: Apocalypse.
