Tron: Legacy is a 2010 American science fiction film produced by Walt Disney Pictures, released on December 16, 2010. It is a sequel to the 1982 film Tron. Joseph Kosinski makes his feature film directorial debut with Tron: Legacy, while the previous film director, Steven Lisberger, returns as a producer. Jeff Bridges reprises his roles as Kevin Flynn and Clu, while Bruce Boxleitner reprises his roles as Alan Bradley and Tron. Garrett Hedlund portrays Flynn’s now-adult son, Sam. The other cast members include Olivia Wilde, Beau Garrett, and Michael Sheen.

For twenty years, Sam Flynn (Garrett Hedlund) has been haunted by the mysterious disappearance of his father Kevin (Jeff Bridges), an innovative software programmer and former CEO of ENCOM International. During a board of director’s meeting before the launch of the twelfth version of ENCOM’s operating system, Sam breaks in and releases it to the public for free while simultaneously uploading a malicious program into ENCOM’s mainframe. He is subsequently caught and later released by the police. Later that night an executive consultant for ENCOM and friend of Kevin, Alan Bradley (Bruce Boxleitner), sends Sam to investigate a mysterious page originating from the long abandoned Flynn’s Arcade. While searching, Sam finds his father’s office hidden beneath the arcade. While attempting to find information within his father’s computer, he activates the laser which transports him to the Grid, a world existing inside the computer.

Sam is quickly caught by The Grid’s sentinels and sent to the Gladiatorial Games. After beating his first opponent and attempting to escape, he is pitted against the master warrior Rinzler. He is subdued and exposed as a human user rather than one of The Grid’s programs. Sam is taken before a figure identical to his father at a younger age, who is revealed to be Clu, a program written by Kevin Flynn. Clu forces Sam into a light cycle battle, which he nearly wins before his lightcycle is destroyed. Before Clu can kill Sam, Quorra (Olivia Wilde) intervenes and takes Sam away from the stadium to a hidden fortress ‘off-grid’, home of Kevin Flynn. Upon meeting, Sam’s father explains this Grid is his creation, built with the assistance of Clu and Alan’s program, Tron. While working on The Grid, a new life form known as isomorphic algorithms (ISOs) manifested, with the potential to unlock huge mysteries in almost every field of science. However Clu, built with the command of creating a “perfect system”, saw the ISOs as imperfect beings, and betrayed Kevin, seemingly murdering Tron and taking over the Grid to enact genocide upon the ISOs. To Sam’s dismay, his father reveals he will not be pursuing an escape through a portal open to the human world that will close within one mili-cycle, which is equivalent to eight hours, citing that the risk of being captured by Clu to be too great.

Upset at the idea of losing his father again and being stuck within the grid, Sam retreats to his room. Likwise displeased, Quorra gives Sam information leading him to Zuse, who she believes may be able to provide safe passage out of The Grid while neutralizing Clu. While searching for Zuse, Sam meets Gem, one of the Sirens, who armed him for the games. She tells him that she can lead him to the person he needs to find and takes him to the End of Line club, run by Castor, who is later revealed to be Zuse. However, before he can help Sam escape, Clu’s forces arrive and fight breaks out. During the fight, Kevin and Quorra arrive to help Sam. In the fray, Quorra’s arm is cut off. Sam, Kevin and Quorra are able to escape, but not before Kevin’s disk, which also acts as the master key to the Grid, is stolen. Castor offers the disk to Clu in return for control of the city, betraying Sam. Clu takes the disc and proceeds to destroy the club, killing Castor and Gem.

While Kevin is healing Quorra, she is revealed to be the last ISO. The three arrive at a station where Clu addresses an army of programs that he has repurposed, revealing he plans to use Kevin’s disk as a means to send them into the human world, so they can continue to “perfect” it. Quorra sacrifices herself as a distraction to Rinzler so that Sam and Kevin may safely enter the station, at which point Kevin realizes that Rinzler is in fact Tron who has been reprogrammed by Clu. Sam then rescues Kevin’s disc and saves Quorra while Kevin commandeers one of Clu’s aerial fighters. The three get away and head for the portal. Clu discovers the breach and pursues the three with Tron. Sam, Kevin and Quorra fend off most of the pursuers, leaving only Tron and Clu . Tron has a flashback of himself telling Kevin to run and save himself and declares that he “fights for the users” before attacking Clu, allowing the three to arrive at the gate to the portal. However, Clu steals Tron’s fighter, leaving Tron to drown in the ocean below, and arrives at the portal before the three. Kevin sacrifices himself by merging with Clu and destroying him while allowing Sam and Quorra to escape through the portal with his disk. Returning the human world, Sam downloads the master key and returns to the arcade where he tells Alan that he will start working at ENCOM on Monday, naming Alan as chairman. He then takes Quorra to show her a sunrise, as she had expressed interest in seeing one earlier in the film

The original character of Yori does not appear in the sequel. According to online media Sci Fi Wire: “Fans have been lobbying for actress Cindy Morgan to be in the movie”. There are active campaigns online, such as “Yori Lives” on Facebook, which is independent of Morgan herself. “All I know is what I’m seeing online,” Morgan said. “I am so thrilled and touched and excited about the fan reaction and about people talking about the first one and how it relates to the second one. I can’t tell you how warm a feeling I get from that. It just means so much.” No one from Tron: Legacy had contacted Morgan, and she did not directly speak with anyone from the Joe Kosinski-directed sequel.

As Dr. Lora Baines, Cindy Morgan appeared with Bruce Boxleitner (as Alan Bradley) at the Encom Press Conference in San Francisco, April 2, 2010.
