The 42-year-old said he has approached screenwriter Jonah Nolan to brainstorm ideas for a new storyline, which will be helmed by original director Paul Greengrass, reported Deadline.
"We just don't have a story, and we haven't had one. I quietly went to Jonah Nolan, because he and his brother Chris did such a brilliant job on 'Batman' and that whole mythology. I just said, 'Can you put your brain on this? I can't figure it out.'
"And he took a run at it and he couldn't crack it either. Paul and I have been talking about it for years. And we can't quite see what the movie would be. If we could get line of sight on that," Damon said.
