Should Jack Black appear in The Flash movie as Green Lantern? Well before Ryan Reynolds played the superhero on the big screen, Black was attached to star in a comedic version of the movie, with former Conan O’Brien writer Robert Smigel writing the script.
As to whether or not Green Lantern will even be in The Flash, that is unclear, but Jack Black has seemingly been preparing just in case.
As for his chances of ever playing Green Lantern, Jack Black wasn’t optimistic when asked about it in 2015.
The Flash is going to restart everything, which means Jack Black could very well appear in the movie.
