(CNN)Olivia Wilde and Garrett Hedlund are set to return for Disney's "Tron 3." The pair will reprise their characters from 2010's "Tron: Legacy" in the sequel, which is being directed by Joseph Kosinski. "Legacy" was the sequel to the 1982 sci-fi film that took place inside a computer world known as the Grid and starred Jeff Bridges and Bruce Boxleitner. While not a hit at the time, it later drew a big cult following and became an influence on filmmakers and pop culture. Decades later, Disney revisited the world with "Legacy." The story revealed that the computer-programmer character played by Bridges had a son (Hedlund) who jumped into the Grid to find his father. Wilde was Quorra, an algorithm-made-flesh who also happened to kick butt.
