Jared Leto was announced as the TRON franchise’s new star in 2017. And yes, that was 7 years ago! Few plot details have been revealed except for Leto playing the title role of Ares, a video game character who finds his way into the real world.
Hmmmm! Isn’t the digital world of TRON the true star of that franchise? I’m thinking “yes”. So having a character from that world come into this one, feels to me like an over-used fish-out-of-water trope. But hey, it worked for the 3rd PLANET OF THE APES movie, The Live-Action HE-MAN movie, ENCHANTED, BEASTMASTER 3, and countless others. So maybe it will work this time around too.
