Recently, a movie came out called Project Hail Mary, based on a book by the same author as the Martian. The movie got great reviews and is doing well at the box office. Project Hail Mary is directed by Phil Lord and Chris Miller, a director/writer duo with a pretty fantastic record. In an interview for Project Hail Mary, the duo mentioned how they wrote a treatment for a Flash movie that they called pretty different from what we ended up getting and they’re not going to reveal anything about it in case DC Studios is still interested. They even said it’s a good idea they’re afraid they won’t be able to use someday.
