The Grid from Tron is home to a couple of major locations, including Argon City and Tron City - here's how they were formed. Computers and video games have become such a major part of the culture it's almost hard to recall a time when they were both considered niche topics. This was the case when the original Tron was released back in 1982. The film starred Jeff Bridges (Iron Man) and featured cutting edge computer animation for the time. While it wasn't a major success it gained a cult following in the years that followed.
It eventually earned a sequel with 2010's Tron: Legacy. The story followed Sam Flynn, the son of Jeff Bridges' Kevin, as he gets sucked into the virtual reality of The Grid. Once inside he's forced to take part in a series of games, including the now iconic Light Cycle match while searching for his missing father. While the sequel received mixed reviews for its story, the beautiful visuals, action sequences and score by Daft Punk were all praised. While Tron 3 was greenlit and set to film in 2015 it was abruptly cancelled by Disney, and while there were rumors a soft reboot starring Jared Leto, another entry has yet to materialize.
An animated series also arrived in 2012 titled Tron: Uprising, featuring the voices of Elijah Wood and Mandy Moore (47 Meters Down). This show was set between the first and second movies and filled in the gaps from when Clu - a corrupt program created by Kevin Flynn in his own likeness - took over The Grid. The show takes place in Argon City, which is one of a number of key locations found in the Tron system. Kevin Flynn created The Grid as a digital frontier where time moves at an accelerated pace, allowing users to make scientific breakthroughs at a much faster rate than in the real world.
The look of Tron's Grid is uniformly black with no daylight to speak of. Everything in the system is centered around Tron City, a vast metropolis where everything is highlighted in bright neon. The city was originally populated with programs designed by Flynn himself which go about their lives like regular people, including hanging out in clubs and playing sports at the Game Arena. Over time, naturally evolving programs known as ISOs emerged from The Grid's Sea of Simulation, but while Flynn was overjoyed with this development, it eventually led Clu to rebel and seek to wipe them out. Tron: Legacy's Quorra (Olivia Wilde, Booksmart) is the last known surviving ISO following Clu's purge.
While Tron City is the center of all activity in The Grid, Argon City is located in a little corner of the system. That said, its design is more complex than Tron City and it includes The Coliseum for Disc War games and Light Cycle battles. It also features an elaborate transport system and huge park. While Tron's Grid may have been designed as a new frontier for creativity and freedom of thought, Clu's brutal regime suppressed a lot of Flynn's original intent.
