Disney is in the early stages of a Tron reboot starring Jared Leto as the star, according to The Hollywood Reporter. The script is reportedly based on an unused script for a follow up to 2010's Tron: Legacy, but would not be a direct sequel.
Leto is reportedly in talks to play a character named Ares. Not much else is known about the reported story, or if it will have any ties to the previous Tron films. There is no indication of what this could mean for Leto's potential involvement as the Joker in future DC films.
No projected release date for the project has been set.
