The concept and ideas for a third film continued behind the scenes, from August 2016 to March 2017, when
Jared Leto was announced to have signed on to co-star as a new character named Ares.

[31] In June 2020 the Walt Disney Studios President of Music & Soundtracks, Mitchel Leib, stated that while the studio hopes that Kosinski will return to the franchise, the studio is currently searching for a director. He also confirmed that the intention is for
Daft Punk to once again serve as
composers on the
film soundtrack score.

The DisInsider provided an update on the project confirming that Leto and the cast from
Tron: Legacy will co-star in the film, while stating that the company is looking at new directors.

the original video game that he played as a child as being influential in his career.
